Towards All-Polymeric Cochlear Implant Micro-Electrode Arrays

Cochlear implants (CIs) are the most effective solution to treat severe-to-profound hearing loss. These medical devices mimic and replace the function of the damaged structures of the cochlea. To this date, more than 700,000 individuals worldwide have benefited from CIs. However, state-of-the-art CIs do not provide a natural and high-quality...

Towards All-Polymeric Cochlear Implant Micro-Electrode Arrays

This paper shows that PEDOT:PSS is an excellent material for all-polymeric cochlear implant micro-electrode arrays. Initial experiments have shown a high conductivity of 230 S/cm for PEDOT:PSS samples, which dramatically decreased to 0.48 S/cm after 3 hours of UV treatment. Electrical characterisation of PEDOT:PSS electrodes reveals that its...
