Just a few years ago, the word exoskeleton meant something we see in a movie that a human actor wears to fight off aliens. But now, exoskeletons are reality, helping workers to ease strain and prevent injury.

Exoskeletons are wearable devices that augment, enable, assist, and/or enhance physical activity. One of the main reasons for exoskeleton successes has been the popularity of exosuits – soft shell textile-based exoskeletons that are more comfortable and lighter weight.

HeroWear, a Nashville, Tennessee-based wearable technology company, has developed Apex exosuit. Developed in conjunction with the Center for Rehabilitation Engineering and Assistive Technology at Vanderbilt University, Apex complements the human body by supporting and assisting the lower-back muscles primarily involved in repetitive lifting and bending activities, reports HeroWear.

Some exoskeleton devices use motors and batteries (or some other power source) while others like the Apex are passive, using bands or springs to provide assistance. More specifically, Apex exosuit is quasi-passive, which means you can turn the assistance on or off as needed.

Back injuries are some of the most common ailments in the workforce worldwide. Injuries sustained from physical fatigue and strain lead to lost wages and lost productivity, costing billions. Low-back pain costs Americans at least $50 billion in health care costs each year.

What sets Apex exosuits apart from others?

• Apex weighs only 3 pounds but it takes 50 pounds of strain off your back every time you lift an object. With no motors or batteries.
• The suit provides strength when you need it and gets out of your way when you don't. This is accomplished through a patent-pending on/off function, activated by a single, easy-to-use switch, which is unique in our market.
• This is the world’s first female-specific exosuit. The Apex follows a modular design that allows custom components for each part of the suit, including components designed specifically with females in mind. These exosuits take a one-size-fits-all approach, without specific fitting for females.
• While other exosuits use batteries or other power sources, Apex is nonpowered. It does not need to be recharged each workday.
