Rockley Photonics, a leading global silicon photonics technology company, today revealed its complete full-stack “clinic-on-the-wrist” digital health sensor system.
Many wearables use green LEDs to monitor heart rate, but Rockley's sensor uses infrared spectrophotometers that can detect and monitor a much wider range of biomarkers to dramatically increase the functionality of wearable devices. The sensor non-invasively probes beneath the skin to analyze blood, interstitial fluids, and various layers of the dermis for constituents and physical phenomena of interest.
Moreover, Rockley’s innovative architecture delivers several milliwatts of optical output power per wavelength channel, which is key to achieving the high signal-to-noise ratio required for signal analysis from a small wearable.
Rockley’s full-stack sensing solution features a wristband that contains the sensor module and communicates with custom cloud-based analytical engines via a Rockley smartphone app. The wristband will be used in a sequence of in-house human studies in the coming months, reports BusinessWire.
“Our full-stack sensor solution, which brings together optical and electronic hardware, firmware, algorithms, and cloud-based analytics, is an exciting milestone on our roadmap. Our reference designs will significantly aid our customers and partners with the deployment of our technology and accelerate their own scalable, high-volume product delivery,” said Dr. Andrew Rickman, chief executive officer and founder of Rockley Photonics. “We believe that combining machine learning algorithms with continuous monitoring of an extended set of biomarkers from accessible wearable devices will provide new actionable insights to enhance and transform digital healthcare.”
Rockley is initially targeting the consumer electronics market, in which significant advances in digital personal health and fitness monitoring have occurred in recent years. Rockley is also actively pursuing the application of its technologies with leading medical device companies as biomarker monitoring can advance digital health applications and improve disease prevention, detection, and management.
Formed in 2013 by Dr. Andrew Rickman (who previously founded the first commercial silicon photonics company, Bookham Technology), Rockley develops a comprehensive range of photonic integrated circuits and associated modules, sensors, and full-stack solutions. From next-generation sensing platforms specifically designed for mobile health monitoring and machine vision to high-speed, high-volume solutions for data communications, Rockley is laying the foundation for a new generation of applications across multiple industries. Rockley believes that photonics will eventually become as pervasive as micro-electronics, and it has developed a platform with the power and flexibility needed to address both mass markets and a wide variety of vertical applications.
