ABSTRACT:
The invention provides an array of electrodes, suitable for use as an auditory prosthesis. The array comprises an electrode body formed from an electrically insulating flexible material, preferably at least one annulus of an electrically insulating flexible material which is formed separately from the body and adhered thereto, at least one electrode positioned concentrically about each of the at least one annulus or electrode body, with the surface of each electrode being recessed and being exposed. The invention also provides a method for fabricating such an electrode array.
