New functional electrical system using magnetic coils for power transmission and control signal detection

In order to improve the Functional Electrical Stimulation system, we consid ered new methods of power transmission to the electrodes and control of the system. Concerning power transmission, a method is proposed to directly su pply electric power to the electrodes by magnetic coupling without the use of electric wires. Selective power transmission to two electrodes is studie d experimentalIy. Power transmissions at frequencies of 96 kHz and 387 kHz are sent separately to secondary circuits, and about 5 electrodes can be us ed. Concerning control of the system, a new control method that uses auricu lar movements is proposed. The effect of electrical stimulation is examined in the process of acquiring voluntary auricular movement. The acquisition method along with biofeedback or functional electrical stimulation is effec tive to some extent.
