Minneapolis-based neuro-AI company Fasikl received FDA 510(k) clearance for its Felix NeuroAI Wristband for tremor-related functional limitations in the upper limbs in adults with essential tremor.

“The Felix wristband represents a significant step forward in noninvasive, personalized treatment options for essential tremor,” said Rajesh Pahwa, M.D., Laverne and Joyce Rider Professor of Neurology at the University of Kansas School of Medicine, Director of the Movement Disorder Program at The University of Kansas Health System.

“For many patients, current treatment options fall short — pharmaceutical treatments are helpful for less than 50% of the patients, and deep brain stimulation and focused ultrasound, while effective, require surgical intervention. This new AI wearable wristband backed by clinical evidence is an effective treatment option in patients with essential tremor.”

Essential tremor is the most common type of tremor disorder, affecting approximately 7 million people in the U.S., and is about seven times more common than Parkinson’s disease. It causes involuntary, rhythmic shaking, most often in the hands, which can make simple and everyday activities like drinking from a glass or tying shoelaces difficult. Traditional treatment options are limited, with oral medications providing inconsistent relief and often accompanied by undesirable side effects. Surgical interventions such as deep brain stimulation (DBS), while effective, require invasive procedures, carry surgical risks, and may not be suitable or desirable for all patients, particularly older adults or those with coexisting health conditions, Fasikl said in a press release.

Unlike surgical or pharmacologic interventions, Felix is a noninvasive, wearable device that effortlessly connects to Fasikl’s cloud-based AI platform, enabling continuous brain-AI co-adaptation and personalized therapy. Worn on the wrist, it uses the cloud to dynamically adjust stimulation, offering all-day symptom relief while seamlessly fitting into the wearer’s lifestyle.

The FDA clearance of Felix is supported by compelling data from the TRANQUIL study, a randomized, double-blind, sham-controlled trial that met its primary endpoint. Results showed that the Felix wristband significantly reduced tremors and displayed statistically and clinically significant improvement in the users' ability to perform daily activities compared to those using the sham device (“placebo effect”).

“FDA clearance of Felix marks a defining moment for Fasikl and the millions of people living with essential tremor who have long been underserved by existing therapies,” said Zhi Yang, Ph.D., CEO of Fasikl. “This breakthrough in noninvasive, intelligent, and personalized neuromodulation marks the emergence of AI therapeutics in disease treatment. It offers a new option that is potentially more effective, safer, and more scalable. Our next step is to execute the commercialization plan to support Felix’s initial product launch."

The Felix NeuroAI Wristband will be available by prescription through healthcare providers in select U.S. regions starting in 2025, with nationwide availability expected in 2026.

Sony announced the launch of REON POCKET PRO wearable thermo-device kit, the latest premium addition to the REON POCKET series of products that can be worn around the neck to cool or warm the part of the body that the device is in contact with.

For the first time in the REON POCKET series, REON POCKET PRO features two independent thermo-modules (DUAL thermo-modules). In addition, it features a newly developed heat-dissipating fan offering approximately twice the airflow compared to the previous model, with a newly designed heat-dissipation mechanism. REON POCKET PRO offers several further enhancements from the previous model with approximately twice the cooling area, up to twice the heat-absorbing performance, and up to twice the operating time5, Sony said in a press release.

REON POCKET PRO is equipped with two independent thermo-modules (DUAL thermo-modules), approximately doubling the cooling/warming area compared to conventional models.

The DUAL thermo-module is a new mechanism in which each thermo-module is driven alternately with varying intensity to sustain cooling. In addition, a newly developed heat-dissipating fan with twice the airflow and a newly designed heat-dissipation mechanism deliver improved heat absorption, with improved cooling performance of up to approximately twice that of the previous model.

As a further enhancement, the upgraded battery delivers approximately 34 hours at COOL Level 1 and up to double the operating time of the previous model.

The accuracy of AUTO START/STOP, which automatically starts or stops the cooling and warming by sensing the condition of the unit and the user's mounting/removal motion, has been improved.

In addition, sensors on the main unit and a unique algorithm have evolved the operating time when using the SMART COOL mode. The enhanced SMART COOL mode intelligently adapts to your environment by analyzing user behavior, temperature, and humidity to deliver powerful, efficient cooling for up to 15 hours.

The new internal heat-dissipating structure has achieved a compact size that remains inconspicuous, even in business environments. The chassis features a light gray color that blends in seamlessly and remains inconspicuous.

The operating noise has been reduced by approximately 50% compared to conventional models, delivering significantly quieter performance. In addition, control buttons located on the sides support basic operations, such as switching between COOL and WARM modes and selecting different levels, even when a smartphone is not available.

The design of the main unit has been improved, with the cooling/warming area now approximately twice larger than before. This area is tilted at the bottom of the main unit to better fit the body shape.

The neckband’s flexibility has been improved by increasing the diameter of the mechanical flexible tube surrounding the wire frame at the center of the band. Additionally, a new silicone extension has been added at the tip of the band for extra comfort.

Pricing and Availability

REON POCKET PRO will be available to pre-order in United Kingdom, Germany, Austria, France and Spain. It will be available in Italy and Switzerland from June onwards.

REON POCKET PRO is available in the following kit:

RNPK-P1T: REON POCKET PRO main unit, neckband, and REON POCKET TAG, with an approximate price of £199 in the UK and €229 in selected European markets.

The Scottish indie brand UNA launched "the world's first" repairable & upgradeable GPS sports watch, the UNA Watch, just a few weeks after preorders for the revived Pebble Core devices opened.

In addition to fitness capabilities like HR zones, pace, laps, and (after launch) downloadable GPX routes, the UNA Watch Kickstarter lists continuous heart rate, blood oxygen, steps, and floors climbed in standard settings.  It boasts a 10-day battery life and dual-frequency GPS, reports Android Central.

It's interesting to note that it uses the same Cortex-M33 coprocessor as the Pixel Watch 3, minus the Snapdragon's draining battery.

Instead of using a proprietary wire, the UNA Watch charges via a straightforward USB-C port. You can even purchase and install modular extras like music storage or a microphone/speaker combo.  Additionally, there won't be any subscriptions.

For an additional $40, you can get the dev tool to add your own firmware and apps!

Related New Partnership Launches Two Streamliners

Pebble is far less focused on fitness. Both UNA and Pebble however, adhere to the open-source, enthusiast attitude that allows users to add their own sensors or write their own code as needed.  Theoretically, the community will expand the UNA Watch's small feature set, much like Pebble requested community assistance in creating new software.

To the detriment of everyone, wristwatch manufacturers have shifted away from allowing independent developers to access their proprietary platforms. Devices like UNA and Pebble are crucial for this reason.

In addition to introducing additional data points like blood pressure and glucose, several wearable brands are focusing on providing medical-grade health tracking. Others, like Garmin, are putting all of their money on AI as a ruse to charge more for its Connect Plus subscription's premium features.

In essence, the heavyweight era of smartwatches is upon us, where companies jam LLMs onto your wrist and consult doctors for more precise data.  While it is fascinating in its own right, the fact that every watch needs a long list of functions to compete means that there is little opportunity for experimentation on the part of smaller brands, small teams, or independent developers.

Years later, you can add new features or change items by unscrewing everything yourself with the UNA Watch. They will decide which new modules, like the microphone/speaker for Bluetooth calls, to create based on community requests and the Kickstarter comments.

At first, Pebble experimented with allowing users to use "smart straps" to enhance their watches after the fact. With the exception of the modules fitting straight onto the watch itself, UNA seems to carry on that tradition. How many modules you can add will be the question.

There are numerous early-bird offers available to save $75 off the final list price during the UNA Watch Kickstarter, which runs until May 2. August 2025 is when it is anticipated to ship. Pebble's new watches, which have lower costs but a later planned release date of December 2025, are also available for preorder right now if you're more interested in that brand.

Garmin claims that their new armband is ideal for tracking your sleep without having to fasten a device to your wrist. It is made to be comfortable throughout the night.

The Index Sleep Monitor is an ultra-comfortable and lightweight smart sleep band that tracks sleep for a more comprehensive view of overall fitness and recovery. Featuring up to 7 nights of battery life with continuous Pulse Ox tracking, the Index Sleep Monitor is worn on the upper arm and tracks sleep stages, heart rate variability (HRV) status, breathing variations, skin temperature and more to calculate a sleep score for users and provide valuable insights about their health1. After a night of sleep, the data seamlessly syncs to the Garmin Connect smartphone app and can be combined with metrics from a compatible Garmin smartwatch to fill in gaps in data for users who don’t wear their watch at night or are looking to better understand how well they recovered, Garmin said in a press release.

“We are thrilled to add the Index Sleep Monitor to our suite of innovative health and wellness products. Wearing this smart sleep band every night can provide in-depth sleep insights and a more complete picture of fitness and recovery so users can wake up ready to seize the day,” said Susan Lyman, Garmin Vice President of Consumer Sales and Marketing.

Rest and recover

Throughout the night, the Index Sleep Monitor tracks the following sleep and recovery metrics, which can then be viewed in Garmin Connect:

• Sleep score: Every morning, receive a personalized score (0-100) for last night’s sleep based on sleep duration, stress, sleep stages and more.

• Sleep stages: View light, deep and REM sleep stages and when they occur during the night.

• HRV status: See last night’s average HRV and status (balanced, unbalanced, low or poor). After several nights of wear, the smart sleep band will establish a personal baseline to help provide a better understanding of recovery and overall wellness.

• Pulse Ox: Track blood oxygen saturation during sleep1.

• Breathing variations: Used in conjunction with Pulse Ox, view and better understand shifts in breathing patterns while sleeping1.

• Respiration: View respiration rates throughout the night.

• Skin temperature: Track skin temperature changes, which can be related to recent activity, sleep environment, potential illness and more.

• Women’s health tracking: Using skin temperature, women can get more insights into their menstrual cycle, including improved period predictions and past ovulation estimates2. Women can also track their menstrual cycle or pregnancy and get exercise and nutrition education in the Garmin Connect app.

• Body Battery energy monitoring: View energy levels to see if the body is charged or needs more rest. Users who wear a compatible smartwatch while awake can get a more complete picture of their energy levels—day and night.

• Stress tracking: See if last night’s sleep was calm, balanced or stressful.

When it’s time to wake up, the smart wake alarm feature looks at lighter sleep stages during a pre-selected window of time to gently wake users with a light vibration so they feel more refreshed.

Available in two sizes (S-M and L-XL), the Index Sleep Monitor is easy to clean; just remove the module and toss the band into the washing machine on the gentle cycle. It is available now for a suggested retail price of $169.99.

Since February of last year, Swiss watchmaker H. Moser & Cie. and Alpine Motorsports have been partners in Formula 1. Shortly after signing the agreement, the H. Moser & Cie. Streamliner Cylindrical Tourbillon Skeleton Alpine F1 Limited Edition, their first cooperation watch, was unveiled. The H. Moser & Cie. Streamliner Alpine Drivers Edition and the H. Moser & Cie. Streamliner Alpine Mechanics Edition are two timepieces that Moser is celebrating the relationship with for the 2025 Formula One season.  Both are included in a paired set.

In order to create a watch that is in sync with the team's schedule and keeps everyone on track through a succession of notifications and countdowns on race day, the new Streamliner Alpine "Mechanic's Edition" blends aspects of smartwatches and quartz-powered timepieces, reports GQ.

"They need to keep track of timings when they’re working, so we started brainstorming,” says Edouard Meylan, H. Moser & Cie.’s CEO. “We said we don't want to create a connected watch per se, but maybe we can create a Formula One watch.”

The Mechanic's Edition is one of two new releases that are each limited to 200 copies.  Typically, the "Driver's Edition" would be powerful enough to serve as a talking point on its own. The new piece comes with a skeletonized dial and a beautiful metallic blue PVD steel case. It features a high-end automatic flyback chronograph manufactured by independent specialist supplier Agenhor, in whom H. Moser owns a minority ownership.  But the Mechanic's Edition, a smartwatch with a hybrid analog-digital display and a number of custom features, will make headlines.  Quartz is rarely used by luxury watchmakers, particularly upscale independent companies like H. Moser, and they never enter the smartwatch market.

Related Pebble Bringing Back Its E-Paper Smartwatches

The Streamliner Alpine F1 Mechanic's Edition is developed in collaboration with Swiss wristwatch experts Sequent. It replicates other Moser designs with its analog hours-and-minutes dial and "hidden" digital display.

“I wanted people to be a little bit confused,” says Meylan, who intended to reference the brand’s work with VantaBlack dials in recent years. “It was important that it looks like a Moser watch, but has this element of surprise when the dial flicks on.”

The watch was created with a comprehensive alarm system specifically tailored to the requirements of Alpine's engineers and mechanics, and it was already in use at this weekend's race in Barcelona.  According to H. Moser, the team has received between 60 and 80 of these timepieces overall.  Alerts will remind the team of important times over the weekend, and communications can be sent to specific team members or their teams.  This is critical info because, as Meylan points out, there are strict penalties and even fines for working on the car after the allotted windows or missing deadlines.

Although it is uncommon for a Swiss watchmaker to show anything other than unwavering faith in its creations, the new watch will serve as an intriguing gauge of how affluent collectors feel about adopting cutting-edge technologies.

The Sycamore solid-state speaker, which was introduced last year, has been enhanced by California-based xMEMS Labs to become the thinnest in the world.

Smartwatch manufacturers are packing an increasing amount of functionality into a wearable form factor that doesn't demand gym exercises or bulk up the wrist. Because internal space is limited, xMEMS claims that its innovative Sycamore-W design reduces speaker package volume by up to 70%, freeing up space for sensors and bigger batteries, reports New Atlas.

According to xMEMS Labs, this near-field MEMS micro speaker is only 20 x 4 x 1.28 mm (0.78 x 0.15 x 0.05 in) in size and hardly moves the needle at 150 mg, whereas legacy coil speakers for equivalent applications can weigh up to 3 g and be 3 to 4 mm thick.

Related Zepp Health Integrates ChatGPT into Its Smartwatches

It generates sound waves by using thin-film piezo actuators to stimulate a silicone membrane. With a similar mid-bass response and punchy performance at the higher registers, the design, according to the inventors, requires less back volume than small-form dynamic drivers.

The solid-state design is also robust, with component-level protection against dust ingress that complies with IP58 standards and the ability to tolerate shocks of up to 10,000 g.  According to the launch press release, "These qualities make it ideal for active lifestyle wearables and outdoor-oriented smartwatches and fitness bands."

"Sycamore-W redefines audio for smart watches, combining compact design with robust performance to meet the demands of next-generation wearables," said Mike Housholder, xMEMS VP of Marketing and Business Development. "As the wrist becomes a key interface for ears-free, hands-free AI interactions, Sycamore-W empowers manufacturers to deliver premium audio in smaller, lighter, more durable devices.”

Researchers at the University of Science and Technology of China have developed contact lenses that enable people to see beyond the visible light range, picking up flickers of infrared light even in the dark – or with their eyes closed.

Yuqian Ma and his team have combined conventional soft contact lenses with 45 nanometre particles consisting of gold, sodium gadolinium fluoride, ytterbium and erbium ions.

According to the team's findings published in the scientific journal Cell, upconversion contact lenses (UCLs) transform infrared light with wavelengths ranging from 800 to 1,600 nanometers into visible light, reports DW.

The energy of the long infrared light waves is enhanced by the nanoparticles.  They accomplish this by transforming infrared light into the three main hues that the human eye can perceive.

The researchers was able to somewhat offset this by adding more lenses, but one disadvantage is that the final images are extremely blurry due to the light being scattered by the nanoparticles in the lenses.

Night vision goggles, which magnify weak infrared signals and make them visible, are still far more effective than infrared contact lenses.

Related Dubai Startup Launches Iron Man Inspired Contact Lens

The mice's behavior demonstrated that they could see in the dark when the team initially put nanoparticles into their retinas.

Since the recently created contact lenses don't require injections into our retinas, they are far more useful.

Humans demonstrated the ability to identify letters, patterns, and flashing infrared signals in the dark during experiments.  Additionally, because infrared light can easily pass through eyelids and normal visible light does not interfere with picture creation, infrared lenses perform even better when the eyes are closed.

When hunting in the dark, the ability of certain animal species to detect infrared light is quite useful.  Infrared light is not perceived by them as "light" in the sense that humans do.  Rather, they sense the heat radiation that things emit.

This aids in orientation and nighttime hunting for a number of cold-blooded reptiles, including snakes (pit vipers and rattlesnakes), some fish (cichlids and piranhas), amphibians (bullfrogs), and bloodsucking insects (mosquitoes and bugs).

Warm-blooded animals — such as humans, other mammals and birds are unable to sense infrared light because their eyes lack the proper receptors, and the heat radiation from their bodies also obstructs their ability to see infrared light.

The developers claim that the glasses might be applied to cryptography or encryption, surgery, or the defense against counterfeiting.

This is due to the fact that infrared light is what, for instance, makes invisible markings or features on documents apparent.

Because the lenses make heat-emitting items visible, they could also be utilized to rescue people in low-visibility situations.  Many critics, however, question this because night vision systems are both much more powerful and much easier to use.

Germany's Karlsruhe Institute of Technology (KIT) developed smart earphones that can check out your vitals as you listen to music. Developed by Dr. Tobias Röddiger and colleagues, the OpenEarable 2.0 earphones do, can measure over 30 physiological parameters.

The OpenEarables, wearable is currently available for preorder at a price of €2,348 (about US$2,566).  Because the earbuds and the software that goes with them are open-source, anybody can modify them and share the results with other users, reports New Atlas.‍

The OpenEarables might theoretically be used in applications like workplace safety or sporting performance analysis in addition to its evident use in the medical field.

Indeed, stereophonic music streamed from a linked smartphone can be played back by the devices.  Sensor data sent by the OpenEarables is processed and shown by an app on the same phone.

Related AI-Powered Sleep-Enhancing Earbuds

Importantly, Röddiger told New Atlas that the earbuds can simultaneously collect their physiological data and play music, with none interfering with the other. It should be mentioned, though, that the earphones work only with Android phones that enable Bluetooth LE Audio, which is not yet supported by iPhones.

They can follow the user's heart activity and verify their identification by using two infrasound/ultrasound microphones, one facing into the ear canal and the other out of it. In contrast, an onboard bone-conduction microphone may detect if the user is eating, mouthing words that are not uttered aloud, or grinding their teeth when they are asleep.

Additionally, there is an optical skin temperature sensor for measuring body temperature or tracking ovulation, as well as a blood-oxygen-level-tracking pulse oximeter that can be used to evaluate stress or energy expenditure and identify sleep apnea.  Additional sensors include a 9-axis IMU (inertial measuring unit) that monitors respiration rates and exercise progress, as well as an ear canal pressure sensor that detects feeding and tongue motions.

One 45-minute USB charge of each earphone's battery should reportedly be good for up to eight hours of runtime, depending on usage.

In a monumental move, OpenAI has acquired io, the AI device startup founded by former Apple design chief Jony Ive, in a deal valued at approximately $6.4 billion. This acquisition, which CNBC reports as an all-equity agreement, marks OpenAI's largest to date and includes its existing stake in io, bringing the net payment to about $5 billion.

A New Era of AI Devices

OpenAI CEO Sam Altman hailed the merger as the dawn of the "greatest technology revolution of their lifetimes." He praised Ive, stating, "Jony is the deepest thinker of anyone I’ve ever met. What that leads him to be able to come up with is unmatched." The core mission behind this integration is to "create a family of devices that would let people use AI to create all sorts of wonderful things."

Ive's Continued Influence

Ive, who left Apple in 2019 to establish his "creative collective" LoveFrom, will assume "deep creative and design responsibilities across OpenAI and io." Importantly, LoveFrom will maintain its independence from the broader OpenAI and io integration. Ive co-founded io a year ago with former Apple colleagues Scott Cannon, Tang Tan, and Evans Hankey. The io team, dedicated to developing "products that inspire, empower and enable," will now merge with OpenAI's research, engineering, and product teams in San Francisco to foster closer collaboration.

OpenAI's Growth Trajectory

This acquisition follows another significant investment by OpenAI last month, when it reportedly paid $3 billion to acquire AI-assisted coding tool Windsurf. The current deal with io further solidifies OpenAI's strategic expansion into the AI device market, leveraging Ive's renowned design expertise, which previously shaped iconic Apple products like the iPhone and Mac during his tenure as chief design officer from 1996.

Chinese researchers have presented a novel idea for solar-powered apparel that can control the body temperature of the wearer. The idea, which was developed by Ziyuan Wang and associates at Nankai University, blends cutting-edge flexible solar cells with electrocaloric devices. In a study published in the journal Science, the team outlines its methodology.

The goal of thermoregulating apparel is to maintain a pleasant and safe body temperature in a variety of settings.  In general, it can be divided into two groups: active and passive.  In order to maintain users' comfort, passive thermoregulation makes use of materials that take advantage of absorption, radiation, and the latent heat of phase transitions.

A key advantage of a passive approach is that an external power source is not needed. Passive thermoregulation, on the other hand, typically only works in one way, with clothing having a warming or cooling effect but not both, reports Physics World.

Active materials that use fluidic channels and coolant circulation to accomplish quick heating and cooling are typically used to provide bidirectional thermoregulation.  Batteries, which add weight and require recharging, are typically used to power these systems.  Although it has proven to be a considerable design issue, they might theoretically also be powered by solar energy collection.

“Because of their high energy consumption, it is difficult for active systems to maintain continuous thermoregulation of the human body for a long time through portable, sustainable energy-harvesting devices,” Xingyi Huang and Pengli Li at Shanghai Jiao Tong University write in a commentary article in Science that accompanies Wang’s paper.

Related Adobe’s Digital Dress Changes Patterns

To tackle this challenge, Wang’s team drew from the latest advances in flexible organic photovoltaics. Today, these solar cells can maintain high conversion efficiencies even when contorted into different shapes.

“If such a highly efficient and flexible organic photovoltaic unit could be integrated with a proper thermal management system, then robust, self-sustaining, and thermoregulating clothing could be achieved,” Huang and Li predict.

Wang and associates developed a tiny wearable material in their work by attaching a flexible solar cell to a flexible electrocaloric module.  The latter is a device that reacts to applied electric fields by changing its temperature reversibly.

The electrocaloric module was able to cool the wearer's skin by up to 10 degrees in hot weather when the solar cell was exposed to sunlight.  A tiny, independent battery can be used to store any extra energy.  The wearable can be put into warming mode in the dark, using its stored energy to raise the wearer's skin temperature by up to three degrees. The device can accomplish thermoregulation over the course of a day.

Wang's team hopes that by incorporating this technology into wearable textiles, the invention may result in a new line of useful, solar-powered apparel that aids wearers in adjusting to difficult and complex situations.

Patients frequently conceal their actual feelings from their caregivers or even from their own aware selves. To help health care providers tell the difference, a team led by scientists at Penn State has created a stretchable, rechargeable sticker that can detect real emotions — by measuring things like skin temperature and heart rate — even when users put on a brave face.

Other components include a printed circuit board, wireless charging coil, 5-volt battery and Bluetooth chip. All of these bits and pieces are encapsulated within a waterproof silicone covering, with the whole device measuring about 6 cm (2.4 inches) in length, reports New Atlas.

The strain sensor on the sticker tracks the patient's skin motions along two axes while it is briefly attached to their face. It then wirelessly transmits this information to an app on a nearby cloud-connected smartphone or tablet.

The software's AI-based algorithms can then infer the user's current facial expression, which is undoubtedly connected to their mood. The technology's accuracy in recognizing six common facial expressions—happiness, surprise, fear, sorrow, rage, and disgust—has been over 96% in lab tests.

Related Artificial Intelligence Tool to Predict Mood Swings

Nevertheless, people can fake facial expressions, frequently even unconsciously. Because of this, the app also makes use of real-time data from the blood oxygen, temperature, and humidity sensors.  The system is already nearly 89% accurate at detecting genuine emotions elicited by watching different video snippets using this combination of data.

The technology may enable doctors to remotely monitor their patients' psychological health through the internet, as the data is processed in the cloud.

"This is a new and improved way to understand our emotions by looking at multiple body signals at once," says Cheng. "People often don't visibly show how they truly feel, so that’s why we’re combining facial expression analysis with other important physiological signals, which will ultimately lead to better mental health monitoring and support."

Georgia Tech researchers have developed tiny brain sensor that can be inserted into the minuscule spaces between hair follicles and slightly under the skin. The sensor offers high-fidelity signals and makes the continuous use of brain-computer interfaces (BCI) in everyday life possible.

BCIs create a direct communication pathway between the brain's electrical activity and external devices such as electroencephalography devices, computers, robotic limbs, and other brain monitoring devices. Brain signals are commonly captured non-invasively with electrodes mounted on the surface of the human scalp using conductive electrode gel for optimum impedance and data quality. More invasive signal capture methods such as brain implants are possible, but this research seeks to create sensors that are both easily placed and reliably manufactured, reports Georgia Tech.

Hong Yeo, the Harris Saunders Jr. Professor in the George W. Woodruff School of Mechanical Engineering, combined the latest microneedle technology with his deep expertise in wearable sensor technology that may allow stable brain signal detection over long periods and easy insertion of a new painless, wearable microneedle BCI wireless sensor that fits between hair follicles. The skin placement and extremely small size of this new wireless brain interface could offer a variety of benefits over traditional gel or dry electrodes.

Related Connect Brain Implant with Robotic Arm

“I started this research because my main goal is to develop new sensor technology to support healthcare and I had previous experience with brain-computer interfaces and flexible scalp electronics,” said Yeo, who is also a faculty member in Georgia Tech’s Institute for People and Technology. “I knew we needed better BCI sensor technology and discovered that if we can slightly penetrate the skin and avoid hair by miniaturizing the sensor, we can dramatically increase the signal quality by getting closer to the source of the signals and reduce unwanted noise.”

Today’s BCI systems consist of bulky electronics and rigid sensors that prevent the interfaces from being useful while the user is in motion during regular activities. Yeo and colleagues constructed a micro-scale sensor for neural signal capture that can be easily worn during daily activities, unlocking new potential for BCI devices. His technology uses conductive polymer microneedles to capture electrical signals and conveys those signals along flexible polyimide/copper wires — all of which are packaged in a space of less than 1 millimeter.

A study of six people using the device to control an augmented reality (AR) video call found that high-fidelity neural signal capture persisted for up to 12 hours with very low electrical resistance at the contact between skin and sensor. Participants could stand, walk, and run for most of the daytime hours while the brain-computer interface successfully recorded and classified neural signals indicating which visual stimulus the user focused on with 96.4% accuracy. During the testing, participants could look up phone contacts and initiate and accept AR video calls hands-free as this new micro-sized brain sensor was picking up visual stimuli — all the while giving the user complete freedom of movement.  

According to Yeo, the results suggest that this wearable BCI system may allow for practical and continuous interface activity, potentially leading to everyday use of machine-human integrative technology.

“I firmly believe in the power of collaboration, as many of today’s challenges are too complex for any one individual to solve,” said Yeo. “Therefore, I would like to express my gratitude to all the researchers in my group and the amazing collaborators who made this work possible. I will continue collaborating with the team to enhance BCI technology for rehabilitation and prosthetics.”

UK researchers have developed smart insoles that accurately measure the forces created when a foot hits the ground in the real world. The cutting-edge technology can help athletes perform at their best and avoid injuries, as well as aid in the rehabilitation of injured patients.

Your foot pushes against the ground when you run, jump, or walk, and the ground pushes back in the opposite direction with an equal amount of power.  These are GRFs.  They are important because they affect how our bodies respond and move when we exercise, reports Paul McClure in New Atlas.

In order to create smart insoles that measure GRFs in three dimensions more naturally and correctly, scientists from the University of Portsmouth in the United Kingdom partnered with the tech company TG0. For sports science, rehabilitation, and injury prevention, these insoles offer practical movement analysis.

“We wanted to create an affordable and portable alternative to expensive lab equipment,” said the study’s lead author, Dinghuang Zhang, PhD, a former postgraduate researcher from the University’s School of Computing and current associate in the knowledge transfer program (KTP) at TG0. “These insoles could help athletes improve performance, assist doctors in rehabilitation, and even help people track their movement for general health.”

The ability of the novel insoles to assess the medial-lateral (Fx), anterior-posterior (Fy), and vertical (Fz) components of GRF gives them their three-dimensionality. The side-to-side force is simply referred to as medial-lateral. When you take a step to one side or the other, such as when you make a rapid lateral movement in basketball, it measures the push or pull that happens. The forward-backward force, which gauges the acceleration or braking that takes place when running, is anterior-posterior. The up-and-down force that the ground exerts on your foot as it lands is known as vertical force. It can be viewed as the force that sustains the weight of your body and is typically the strongest of the three. Understanding healthy gait and how it is impacted by injury, muscle fatigue, posture and balance, and neuromuscular diseases requires knowledge of all three.

To monitor foot pressure and movement, the team’s TG0 Smart Insole has an inertial measuring unit (IMU) and integrated pressure sensors. An IMU is a device that has a number of sensors that measure motion by determining the foot's rotation (gyroscope), speed in various directions (accelerometer), and direction of travel (magnetometer). To forecast GRFs, machine learning is fed all of the data collected by the IMU and pressure sensors.

The TG0 Smart Insole was tested by the researchers on five healthy adults of varying heights and body weights. To reduce data variability brought on by muscular stiffness or equipment unfamiliarity, participants initially engaged in a walking and jumping warm-up. After the insole was fitted, patients were instructed to execute a set of exercises on a force plate, including deep squatting, walking and jogging in place, swaying to the left and right, jumping in place, and jumping forward and backward.

The researchers discovered that the insole accurately predicted GRF with an error rate of 4.16% after comparing the GRF data from the insole with the force plate, which served as a reference. The normalized root mean squared error (NRMSE), a metric for predicting accuracy in comparison to gold standard force plate readings, is reflected in the error rate. Although there is a low mistake rate, it is crucial to take into account the environment in which these insoles will be utilized because the allowable error margin may differ based on the application, such as healthcare and rehabilitation versus sporting performance.  NRMSE errors of 8% to 20% have been observed in investigations on alternative GRF measurement techniques, such as motion sensors or pressure insoles, the researchers pointed out.

The smart insoles use Bluetooth low-energy (BLE) to connect to a USB dongle that is connected to a PC.  They include a built-in battery that can gather data constantly for about eight hours.

The researchers anticipate a variety of uses for their smart insoles. They could lower the risk of injury, improve training, and assist athletes in tracking their movements. They might be used by physicians and physical therapists to keep an eye on patients who are recovering from injuries or have movement problems. Additionally, they could gather information to further the study of biomechanics and sports science.

The study was published in the journal Intelligent Sports and Health.

This summer's Club World Cup in the United States will use referee body cameras, giving spectators a distinctive and engaging perspective of the action.  According to Pierluigi Collina, chairman of FIFA's Referees Committee, the innovation would give broadcasters access to film taken straight from the referee's point of view, providing fans with real-time information on pivotal match moments such as goals, fouls, and tactical plays.

“Viewers will get a perspective that’s never been offered before,” said Collina. “It’s not just a novelty—it’s a valuable tool for referee development. Seeing exactly what the referee sees helps us analyze decisions and improve performance.”

According to FIFA, the use of cameras will be on an experimental basis, after being approved last month by IFAB, the FIFA body that decides the laws of the sport, reports OneFootball.

FIFA has stated that, in addition to the cameras, it will implement a new regulation that penalizes goalkeepers for their infamous "time-wasting" by giving the opposition a corner kick if they hold the ball for longer than eight seconds.

Referees hardly ever penalize goalkeepers for "time-wasting," even if there is already a straight free kick as punishment for this.

"We think it's a good chance to offer spectators a new experience, in terms of images taken from a perspective, from an angle of view that has never been offered before," said Pierluigi Collina, president of the FIFA Referees Committee. "It's a combination of new experiences for broadcasters and also for training purposes," he added.

The camera system, which is attached to the headset and placed close to the ear, has already been tested in the Bundesliga in Germany and during a Premier League game in which Jarred Gillett played.  Although both incidents were included in documentaries, the Club World Cup marks a change to live integration.

“This is the first time we’ll see the best clubs from every continent compete in this format,” Collina added. “We’re committed to ensuring officiating meets the highest standards to match the importance of the occasion.”

The new technology has the potential to completely change how referees are educated throughout the world as well as how fans watch games.

A tiny sensor created by researchers at theUniversity of California, Los Angeles (UCLA) can help monitormetabolites—substances your body produces or uses when it breaks down food,medication, or even its own fat and muscle in metabolic processes—much morethoroughly than existing techniques.

This technology could speed up the creationof more potent medications, track how patients respond to treatment, and openup new avenues for the detection and management of illnesses anddisorders.  The sensor's ability to tracknatural biochemical processes, such as the transformation and interaction ofmolecules within our bodies, is very intriguing, reports Abhimanyu Ghoshalin NewAtlas.

"Tandem metabolic reaction-basedsensors," or TMR sensors for short, are what the group from UCLA'sCalifornia NanoSystems Institute labels its inventions.  They monitor metabolites in a manner similarto that of tiny chemistry labs. Tiny electrodes composed of minusculesingle-wall carbon nanotubes serve as the foundation for the sensors. On theseelectrodes, the researchers placed cofactors—helper molecules that facilitatechemical reactions—and enzymes.

The enzymes trigger a chemical reactionwhen a certain metabolite—the molecule they are trying to identify—approachesthe sensor. The target metabolite is the focus of this reaction. Through thisresponse, the sensor may occasionally be able to directly detect themetabolite. In other cases, the enzymes will first change the metabolite into adetectable molecule if it cannot be detected directly. A sequence of actions,such as the body's normal metabolic pathways, may result in this conversion.They are referred to as "tandem metabolic reaction-based sensors"because of their capacity to conduct numerous reactions.

The exchange of electrons is a crucialcomponent of these processes. Electrons may migrate when the enzymes interactwith the metabolite. On the carbon nanotubes' surface, these electron motionsproduce an electrical current. This electrical current is then measured by thesensor. The scientists can determine how much of the metabolite is present bymeasuring the current. Therefore, more of the metabolite indicates a largercurrent, and less indicates a lower current.

In essence, the TMR sensors convert thepresence of metabolites into a detectable electrical signal by using thechemical reactions that occur naturally on a microscopic electrical surface.

These sensors are capable of detecting overtwo-thirds of the many metabolites that the human body produces through aconversion phase. We might be able to get a comprehensive picture of apatient's condition and treatment response from it.

According to the researchers, this methodmay aid in the early detection of cardiac problems and the customization oftherapies to address each patient's unique metabolic needs. By monitoring howathletes' bodies use energy when under stress, it may help them become morephysically fit.  Additionally, TMRsensors may provide insight into how developing medications affect metabolicpathways and suggest strategies for maximizing their benefits.

Northwestern University scientists have developed a pacemaker so small that it can fit inside the tip of a syringe — and be non-invasively injected into the body.

While still years away from being tested in humans, the wireless pacemaker was hailed as a "transformative breakthrough" that could spur advances in other areas of medicine.

The pacemaker, which is smaller than a grain of rice, is controlled by light shone through the skin. The device generates power and squeezes the heart’s muscles after injection through a stint.

In a recently published study, the pacemaker demonstrated its ability to consistently coordinate healthy heart beats in the hearts of rats, dogs, and humans.  Additionally, it is biocompatible and, after brief use, is eventually broken down by the body. The device, which is more than 23 times smaller than earlier bioabsorbable pacemakers, paves the way for minimally invasive implants that wirelessly check on heart health following major surgery or other cardiac issues.

“We have developed what is, to our knowledge, the world’s smallest pacemaker,” said Northwestern bioelectronics pioneer John A. Rogers, who led the device development. “There’s a crucial need for temporary pacemakers in the context of pediatric heart surgeries, and that’s a use case where size miniaturization is incredibly important. In terms of the device load on the body — the smaller, the better.”

“Our major motivation was children,” said Northwestern experimental cardiologist Igor Efimov, who co-led the study. “About 1% of children are born with congenital heart defects — regardless of whether they live in a low-resource or high-resource country. The good news is that these children only need temporary pacing after a surgery. In about seven days or so, most patients’ hearts will self-repair. But those seven days are absolutely critical. Now, we can place this tiny pacemaker on a child’s heart and stimulate it with a soft, gentle, wearable device. And no additional surgery is necessary to remove it.”

Instead of using near-field communication to supply power, the new, tiny pacemaker operates through the action of a galvanic cell, a type of simple battery that transforms chemical energy into electrical energy. Specifically, the pacemaker uses two different metals as electrodes to deliver electrical pulses to the heart. When in contact with surrounding biofluids, the electrodes form a battery. The resulting chemical reactions cause the electrical current to flow to stimulate the heart, reports Northwestern.

“When the pacemaker is implanted into the body, the surrounding biofluids act as the conducting electrolyte that electrically joins those two metal pads to form the battery,” Rogers said. “A very tiny light-activated switch on the opposite side from the battery allows us to turn the device from its ‘off’ state to an ‘on’ state upon delivery of light that passes through the patient’s body from the skin-mounted patch.”

Pulsing with light

The team used an infrared wavelength of light that penetrates deeply and safely into the body. If the patient’s heart rate drops below a certain rate, the wearable device detects the event and automatically activates a light-emitting diode. The light then flashes on and off at a rate that corresponds to the normal heart rate.

Related Ultra-Thin Minimally Invasive Pacemaker

“Infrared light penetrates very well through the body,” Efimov said. “If you put a flashlight against your palm, you will see the light glow through the other side of your hand. It turns out that our bodies are great conductors of light.”

Even though the pacemaker is so tiny — measuring just 1.8 millimeters in width, 3.5 millimeters in length and 1 millimeter in thickness — it still delivers as much stimulation as a full-sized pacemaker.

“The heart requires a tiny amount of electrical stimulation,” Rogers said. “By minimizing the size, we dramatically simplify the implantation procedures, we reduce trauma and risk to the patient, and, with the dissolvable nature of the device, we eliminate any need for secondary surgical extraction procedures.”

More sophisticated synchronization

Because the devices are so tiny, physicians could distribute collections of them across the heart. A difficult color of light could illuminate to independently control a specific pacemaker. Use of multiple pacemakers in this manner enables more sophisticated synchronization compared to traditional pacing. In special cases, different areas of the heart can be paced at different rhythms, for example, to terminate arrhythmias.

“We can deploy a number of such small pacemakers onto the outside of the heart and control each one,” Efimov said. “Then we can achieve improved synchronized functional care. We also could incorporate our pacemakers into other medical devices like heart valve replacements, which can cause heart block.”

“Because it’s so small, this pacemaker can be integrated with almost any kind of implantable device,” Rogers said. “We also demonstrated integration of collections of these devices across the frameworks that serve as transcatheter aortic valve replacements. Here, the tiny pacemakers can be activated as necessary to address complications that can occur during a patient’s recovery process. So that’s just one example of how we can enhance traditional implants by providing more functional stimulation.”

The technology’s versatility opens a broad range of other possibilities for use in bioelectronic medicines, including helping nerves and bones heal, treating wounds and blocking pain.

A group of researchers from UC Berkeley and UC San Francisco has discovered a method to help individuals with severe paralysis regain naturalistic speech, which is a significant advancement in the field of brain-computer interfaces (BCIs).

The long-standing problem of latency in speech neuroprostheses—the interval between a subject's attempt to speak and the sound that is produced—is resolved by this work. The researchers created a streaming technique that converts brain impulses into audible speech in almost real time using the latest developments in artificial intelligence-based modeling.

“Our streaming approach brings the same rapid speech decoding capacity of devices like Alexa and Siri to neuroprostheses,” said Gopala Anumanchipalli, Robert E. and Beverly A. Brooks Assistant Professor of Electrical Engineering and Computer Sciences at UC Berkeley and co-principal investigator of the study. “Using a similar type of algorithm, we found that we could decode neural data and, for the first time, enable near-synchronous voice streaming. The result is more naturalistic, fluent speech synthesis.”

Related The Future of Cognitive Health

“This new technology has tremendous potential for improving quality of life for people living with severe paralysis affecting speech,” said UCSF neurosurgeon Edward Chang, senior co-principal investigator of the study. Chang leads a clinical trial at UCSF that aims to develop speech neuroprosthesis technology using high-density electrode arrays that record neural activity directly from the brain surface. “It is exciting that the latest AI advances are greatly accelerating BCIs for practical real-world use in the near future,” he said.

The researchers also showed that their approach can work well with a variety of other brain sensing interfaces, including microelectrode arrays (MEAs) in which electrodes penetrate the brain’s surface, or non-invasive recordings (sEMG) that use sensors on the face to measure muscle activity, reports Marni Ellery in Berkeley Engineering.

According to study co-lead author Cheol Jun Cho, who is also a UC Berkeley Ph.D. student in electrical engineering and computer sciences, the neuroprosthesis works by sampling neural data from the motor cortex, the part of the brain that controls speech production, then uses AI to decode brain function into speech.

“We are essentially intercepting signals where the thought is translated into articulation and in the middle of that motor control,” he said. “So what we’re decoding is after a thought has happened, after we’ve decided what to say, after we’ve decided what words to use and how to move our vocal-tract muscles.”

To collect the data needed to train their algorithm, the researchers first had Ann, their subject, look at a prompt on the screen — like the phrase: “Hey, how are you?” — and then silently attempt to speak that sentence.

This latest work brings researchers a step closer to achieving naturalistic speech with BCI devices, while laying the groundwork for future advances.

“This proof-of-concept framework is quite a breakthrough,” said Cho. “We are optimistic that we can now make advances at every level. On the engineering side, for example, we will continue to push the algorithm to see how we can generate speech better and faster.”
