چکیده
The paper presents the performance optimization of a MEMS accelerometer based microphone for the fully implantable hearing application. A genetic algorithm is employed to optimize the device geometry parameters satisfying the design constraints. The analytical model run on MATLAB and the simulation model implemented in COMSOL MULTIPHYSICS 4.2 show good agreement. Optimization with Genetic algorithm shows enhanced capacitance of 3.14 pF, displacement sensitivity of 2.49 nm/g and capacitive sensitivity of 2.48 fF/g.

INTRODUCTION: According to the 2015 estimates of WHO, 278 million people have disabling hearing impairment. In India, 63 million people suffer from significant auditory loss. The majority of all hearing loss is sensorineural loss which refers to hair cells damage in cochlea, a snail like structure inside the inner ear which connects to the auditory nerve in the brain. The use of conventional he...
