The development of prosthetic devices increasingly focuses on approaches which allow amputees to control them in a physiological way. A great problem of actual most promising prostheses, myoelectric prostheses, is the absence of sensory feedback, so patients perceive the prosthetic device not as a part of themselves. Different types of electrodes have been proposed to directly interface with the peripheral nervous system at different degrees of invasiveness (i.e Cuff,TIME, tLife). The purpose is restoring motor and sensory activities, in amputees or patients with different kind of neurological injuries. In this work, a system which combines stimulation, recording and elaboration functionalities has been implemented .
