Providing Non-Invasive Sensory Feedback for Transradial Prosthetic Hand Users

Currently there is a large rejection rate and dissatisfaction with prosthetic hands. One primary reason for the rejection of the prosthetic hands is that there is no or negligibly small feedback or tactile sensation from the prosthetic hand to the user, making the prosthetic device less functional. This lack of feedback requires significant reliance on visual information from the user in order to do basic gestures and daily activities, and therefore, can lead to significant cognitive effort. In addition to reducing the need for visual attention, sensory feedback has been shown to increase embodiment and reduce the occurrence of phantom limb pain.
