For anyone who has lost a hand, a functional prosthetic hand is of enormous benefit when it comes to everyday activities. So researchers at Fraunhofer are working as part of an EU research project to improve control of prosthetic hands down to individual fingers. Instead of conventional electrodes that detect nerve impulses in muscle tissue in the arm, these rely on ultrasonic sensors. This means commands can be executed with far greater accuracy and sensitivity. In the next stage, researchers want to make the design bidirectional, with the brain also receiving sensory stimuli from the prosthesis.
