Thought-Controlled Bionic Arm.

Jesse Sullivan lost both of his arms in an industrial accident, but thanks to modern technology, he now has a thought-controlled bionic arms:

The motions are coordinated and smooth because his left arm is a bionic device controlled by his brain. He thinks, "Close hand," and electrical signals sent through surgically re-routed nerves make it happen.

Doctors describe Sullivan as the first amputee with a thought-controlled artificial arm.
