This implant controls hand prostheses by EMG monitoring1 and provides user feedback. The feedback signal is acquired by pressure sensors and applied by nerve stimulation. The development of a new generation of intuitively mind-controlled prostheses is an ongoing field of research. This approach improves the control interface towards the behavior of a real part of the body by two major strategies: i) Extracting a higher functional density by increasing the number as well as the selectivity of the recording electrodes. ii) Integrating a sensory feedback as a sensation to the user that gives him a natural perception when touching or grasping objects with his artificial hand.
