Abstract:
The disclosure relates to 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 at least one support embedded in said array. The disclosure further relates to 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 folded flexible circuit cable connecting the electrode array with an interconnection pad. The disclosure further relates to a method of making a flexible circuit electrode array comprising: depositing a polymer base layer; depositing metal on said polymer base layer; patterning said metal to form metal traces; depositing a polymer top layer on said polymer base layer and said metal traces; heating said flexible circuit electrode array in a mold to form a three dimensional shape in said flexible circuit electrode array, embedding a support at least in the base layer, top layer or between the base and top layer, and/or folding a flexible circuit cable at least once connecting the electrode array with an interconnection pad on the array.
