Design of MEMS Based Polymer Microphone for Hearing Aid Application

This paper presents a condenser microphone for hearing aid application. It gives a brief overview of different types of hearing aids available in the market. The work looks into the principle of operation a of MEMS Condenser Microphone (MCM) for hearing aid application. The stress versus pressure and Displacement versus arch length analysis has been carried out. The simulation work has been carried out in COMSOL Multiphysics using Structural mechanics and in specific Electromechanics.
