NEW DELHI (PTI): Engineers at the Indian Institute of Technology, Kanpur, and (IITK) have developed India’s first bionic prostheses an artificial hand that can be moved by impulses emerging directly from the brain.
The battery powered, electronically controlled hand is intended for accident victims who have lost their hands below the elbow.
Normal hand movements are executed when signals from the brain direct the hand muscles to move. In amputees, these signals are terminated at the stump the site of amputation. The new device picks up the signals from the brain reaching the muscles, and motor drives finger movements. The model can be used to grip and release objects
“This is a will operated system.
An amputee who wants to move fingers just has it will it” said Professor G.C. Ray, a senior ITT research engineer who led the team that developed the device.
