Реферат: In a visual prosthesis electrodes stimulate retinal tissue to induce the perception of light to a user implanted with the prosthesis. The prosthesis must have a return, or common, electrode to make a complete circuit with the retinal tissue. To avoid stimulating tissue with the return electrode, it is advantageous if the electrode is large. The invention involver a flexible circuit electrode array comprising a polymer base layer, metal traces deposited on said polymer base layer, including electrodes suitable to stimulate neural tissue a polymer top layer deposited on said polymer base layer and said metal traces, and a return electrode separate from said stimulating electrodes. The flexible circuit electrode array comprises a secondary coil for receiving visual data; an electronics package electrically coupled to said receiving coil, and a plurality of stimulating electrode electrically coupled to said electronics package.
