Abstract
An artificial cochlea device for processing audio signals by electro-mechanical amplitude changes may be provided. The device comprises a micro-electro-mechanical system (MEMS) microphone comprising a membrane, an electro-mechanical feedback loop embedded in the MEMS microphone. Thereby, the electro-mechanical feedback loop comprises a piezo-electric actuator acting on the MEMS microphone by influencing the membrane's way to swing, such that an electro-mechanical amplitude change of an output signal is achieved.
