Abstract Cochlear implants (CIs) are neuroprosthetic devices that restore hearing in deaf patients. They consist of a linear electrode array surgically inserted into the scala tympani of the cochlea. In this position the array directly stimulates the spiral ganglion neurons (SGNs), bypassing lost or nonfunctioning sensory hair cells. In order to reduce the energy needed to stimulate the SGNs, we attempted to improve the conductivity of the CI electrodes by creating conductive nanocomposites. We assessed the functional modification of CI platinum (Pt) pads by using multi-walled carbon nanotubes (MWCNTs) either alone or in combination with a conductive polythiophene phase, to obtain conductive nanocomposites (NCs).
