Abstract
A novel electrode array is described for ear implant systems such as cochlear implants (CI) and vestibular implants (VI). The electrode array includes electrode wires for carrying electrical stimulation signals. At a terminal end of each electrode wire is an electrode stimulation contact for applying the electrical stimulation signals to adjacent neural tissue. An electrode carrier of resilient material encases the electrode wires and has an outer surface with a plurality of contact openings exposing the stimulation contacts. Multiple bend control elements are distributed along the length of the electrode array to control bending flexibility of the electrode array as a function of a bend radius threshold to be greater for bending less than the bend radius threshold and lesser for bending greater than the bend radius threshold.
