Although there have been many advances in prosthetic technology, truly advanced prosthetic systems will require seamless integration of the intact sensory-motor living system with advanced, highly-functional artificial limbs. The goal of this project was to develop an advanced prosthetic system that uses wirelessly connected electrodes that are implanted within the fascicles of peripheral nerves to provide upper extremity amputees with sensory feedback and further activate volitional control of the prosthesis. I developed a PC interface program that communicates with the wearable systems. The communication program is controlled by a PC and delivers electrical stimulation through the telemetry of the wearable system. I also conducted animal implant testing and evaluated the interface program and electrode implantations. Electrodes were implanted into the fascicles of the sciatic nerve or the phrenic nerve (when recording), and other ends of the implanted electrodes were connected to a telemetry receiving system. Electrical stimulations were delivered to the implanted electrodes using the communication interface program.
