This paper concentrates on developing a self-contained cochlea whose performance is at par with natural hearing. The Artificial Basilar Membrane (ABM) design is done in such a manner so as to get a performance similar to the natural hearing. Finite element analysis was done with the help of COMSOL Multiphysics software. Two materials, Polyvinylidene fluoride (PVDF) and lead zirconate titanate ( PZT 5A) were tested for their performances. Simulation results confirmed the suitability of PVDF material and the chosen design had the characteristics for frequency separation in the range of 1KHz to 10KHz.
