China’s self-powered neural device helps stroke survivors walk naturally

Scientists have developed a lightweight, battery-free device that could help improve the mobility of people with difficulty walking, such as stroke survivors. Developed by researchers in Hong Kong and mainland China, the neural prosthesis uses energy generated by the wearer’s own movements to electrically stimulate their muscles, helping to flex their ankle and restore their natural walking pattern. This could prevent falls for stroke survivors, elderly individuals and others living with...
