A novel device for multi-modal sensory feedback in hand prosthetics: Design and preliminary prototype

This paper presents a new multi-modal haptic device designed to deliver sensory feedback to upper limb amputees using a myoelectric prosthesis. In particular this device conveys to the individual information about (i) contact between digits and the environment through a vibrotactile stimulus and (ii) grip force applied by the prosthesis on objects via force/pressure feedback. The device described in this work may be used both in research and clinical scenarios in the near future due to its limited dimensions, weight and power consumption.
