Design of an Artificial Microelectromechanical Cochlea

Article Preview

Abstract:

The paper presents the first results of research on an artificial cochlea based on a mechanical filter bank that could be produced by MEMS (Micro Electro Mechanical Systems) technologies and power supplied by energy harvesting systems. First, the basic configuration of the artificial cochlea proposed by our team is described. Then, the configuration of mechanoelectrical transducers (polycrystalline diffused piezoresistors) displayed in the first experiment is offered. Finally, the eigenfrequencies of resonant membranes calculated employing finite element systems Ansys and CoventorWare are introduced.
