Low Power Electronic System for Tactile Sensory Feedback for Prosthetics

This paper presents a portable, low power electronic system for tactile sensory feedback for prosthetics. The system provides a prototype based on commercial off-the-shelf components having a wireless portable interface electronics and an array of 32 tactile sensors. The proposed prototype demonstrates to be able to transmit the touched signals with low power energy consumption achieving a battery lifetime of about 22 hours. Experimental results validate the correct functionality of the proposed prototype when different input stimuli have been tested. The proposed system overcomes similar state-of-the-art solutions having higher number of input channels featuring low power and real time operation.
