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

Researchers from Hong Kong and mainland China have developed a novel, lightweight, and battery-free neural prosthesis designed to improve walking mobility. This device utilizes energy harvested from the wearer's own movements to electrically stimulate muscles, specifically aiding in ankle flexion. The goal is to help individuals with walking difficulties, such as stroke survivors, elderly people, and those with other mobility impairments, to restore a more natural walking pattern and prevent falls. The technology operates automatically during walking, integrating energy harvesting and stimulation delivery without external sensors or batteries. The findings were published in Nature Communications on September 2.
