Amputee controls individual prosthetic fingers
From: ScienceDaily - 12/11/2017

Luke Skywalker's bionic hand is a step closer to reality for amputees in this
galaxy. Researchers have created an ultrasonic sensor that allows amputees to
control each of their prosthetic fingers individually. It provides fine motor
hand gestures that aren't possible with current commercially available
devices.

The first amputee to use it, a musician who lost part of his right arm five
years ago, is now able to play the piano for the first time since his
accident. He can even strum the Star Wars theme song.

Barnes' everyday prosthesis is similar to the majority of devices on the
market. It's controlled by electromyogram (EMG) sensors attached to his
muscles. He switches the arm into various modes by pressing buttons on the
arm. Each mode has two programmed moves, which are controlled by him either
flexing or contracting his forearm muscles. For example, flexing allows his
index finger and thumb to clamp together; contracting closes his fist.
