Here is a bionic hand for amputees that allows them to control individual fingers accurately thanks to machine learning and ultrasound technology. Researchers at the Georgia Institute of Technology created a special sensor to allow amputees to control their prosthetic hands with fine motor hand gestures not possible with current commercially available bionic hands.
Thanks to this solution, users can play piano and perform other tasks independently, with more accuracy. Pretty impressive, don’t you think? More info is available here.
