Wireless Brain Control of Prosthetics

I’m Prachi Patel.  Last year, University of Pittsburgh scientists gave monkeys the ability to control a robotic arm just by thinking about it.

A tiny chip implanted in the animals’ brain was the key. It has hair-like electrodes that pick up nerve signals from the brain. Wires carry the signals through the skull. And then computer software converts these signals into a robotic arm’s movements.
