Electrochemical study of potential materials for cochlear implant electrode array

Electrochemical study of potential materials for cochlear implant electrode array (abstract)

Cochlear implants (CIs) are commonly accepted therapeutic devices for clinical use and have restored hearing to more than 230,000 profoundly deaf people. CI devices consists of an external part comprising a speech processor (DSP) a microphone which together receive and convert the sound into a digital data stream using a speech processing...

Thin Titanium Nitride Films Deposited using DC Magnetron Sputtering used for Neural Stimulation and Sensing Purposes

n recent times Platinum (Pt), Iridium (Ir), Iridium oxide (IrO) and Platinum-Iridium (Pt-Ir) are the favorable microelectrode materials. They show excellent electrical and mechanical properties suitable for neural stimulation and sensing/recording purposes. But their long term stability and performance is still in question especially working in...

Design and fabrication of stiff silicon probes: A step towards sophisticated cochlear implant electrodes

Cochlear implants work on the principle of direct electrical stimulation of the auditory nerve. It has advantages to replace their traditional wired electrodes by a high-density thin-film multielectrode stimulation array which is relatively small in dimensions, stable, resistant to electrolysis, and offers batch fabrication capabilities with...
