Abstract
Postoperative medical studies by various groups have shown the relevance of electrode position on the hearing outcome of the Cochlear Implant. There are various types of CI in market that are re-evaluated and changed for its functionality. Prior knowledge of the exact position of the electrode within the cochlea is an important parameter of study to improve the electrical stimulation of the hearing nerve for the implants. Similar studies are performed on the artificial epithelium membrane which involves restoring the function of outer and middle ear without bypassing their functionality and providing solution towards a self sustained implantable cochlea. Different shapes of electrodes are evaluated using various structures in dimensional analysis for improving the displacement and the electric stimulation calculated in terms of voltage. Five designs are modelled and optimized for improving the frequency selectivity for its resonance of an epithelium membrane to function as a biomimetic Epithelium membrane. Simulation studies are carried out using FEA analysis tool to introspect and evaluate the tonotopy of the epithelium membrane in terms of electrode shape and position.
