Luke Skywalker’s Bionic Hand is a step closer to reality according to researchers at the Georgia Institute of Technology. These guys have created an ultrasonic sensor that allows amputees to control their prosthetic sensors individually. The robotic arm can detect which fingers a user wants to move and does the rest.
Plenty of bionic arms with EMG sensors are around. But they are not very accurate. With ultrasound signals and machine learning, it is now possible to make advanced prosthetic arms that can make life easier for many amputees.
