ABSTRACT: In this paper a unified approach of a nerve direct coupled electronic controller for hand prostheses is presented. The study starts with the forearm and hand dynamics analysis in order to achieve a neural interface connecting the peripheral median nerve from the patient’s amputee arm with a prosthetic hand. After identifying the median and the ulnar nerves, the nerve direct coupling system is presented and the command electrodes experimental implantation in the operating amputee arm was performed. The proposed experimental system for the biopotentials generated by a motor nerve fiber using electrodes positioned on the nerve to control a hand prosthesis is shown. The peripheral interface is connected to a prosthetic hand with independent fingers in order to test the possibility of a nervous direct control for fingers motion.
