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
the array.
