Claim One:
1. An addressable wireless implantable micro-electrical stimulator which comprises a photovoltaic device, an energy storage device and circuitry for signal demodulation and excitation control wherein the stimulator contains a control circuit that decodes a signal received by the stimulator and determines whether the stimulator is to be activated or not activated, wherein the stimulator is addressed by the signal a one-way communication channel that transmits the signal via an encoded optical pulse packet to the control circuit, wherein the control circuit is divided into functional blocks which control functions of the stimulator, which functions are comprised of optical power and controls, reset detection, pulse counting, and stimulation, and wherein the optical power and controls includes sets of photodiodes, a first one of sets of photodiodes is connected in series to generate the stimulation current, a second one of the sets of photodiodes is connected in series to generate voltage to run logic circuits, and a third one of the sets of photodiodes is in series with a resistive load to pulse shape an input.
