Summary

Story summary

Researchers in Hong Kong and mainland China developed a lightweight, battery-free neural prosthesis that assists walking.
The prosthesis harvests wearer movement energy to electrically stimulate ankle muscles without external sensors or batteries.
In treadmill and outdoor tests, a few steps powered the device, increasing stride length and speed in stroke survivors.
Researchers said the prosthesis could help prevent falls for stroke survivors, elderly people, and others with mobility impairments.
