This is a neuro-robotic arm brace with sensors that is worn like a sleeve. Where it touches the skin surface it can detect very faint muscle signals. The robotics in the mPower 1000 then engage to assist with moving the arm. Its designed to be worn by people with a weak or partially paralyzed arm and can be worn as an aid, or used as a rehabilitation device that helps the brain relearn arm movement. It weighs just 846 grams and has its controls onboard for easy use.
