An implantable microstimulator system employs a miniature ferrite-cored coil contained with an hermetically sealed housing to receive control signals and operating power from an RF telemetry system. The tiny coil receives the electromagnetic energy which is transmitted from a non-implantable transmitter which generates a code-modulated carrier. Demodulator circuitry in the implantable microcircuit is employed to extract the control information, while applying the electromagnetic energy to power the electronic circuitry therein and charge a capacitor which will provide the electrical stimulation to the living being. The electrical stimulation is delivered by a stimulating electrode which has a waffle-like configuration whereby a plurality of iridium oxide electrode pads, coupled in parallel, so as to be characterized by a long effective edge distance, transfer the stimulating charge. The electrical components of the implantable microstimulator are contained within an hermetically sealed housing formed of a glass capsule which is electrostatically bonded to a silicon substrate.
