Design of the Charge Push-Through Electronics for Fully Implantable Artificial Cochlea

Existing artificial cochlear devices use two separated parts for this purpose: a signal processing unit with transmitter and an implantable receiver with electrodes. This approach is applicable but not fully implantable. A charge push-through electronics, the new complex approach to design a fully implantable artificial cochlea is described in this article. A unique technique for nerve stimulatory output signal generation is discussed. Mechanical parts of the subcircuits were simulated as complex electro-mechanical simulation models in ANSYS, CoventorWare, Matlab and SPICE environment. The whole electronics simulation model for energy harvesting circuits was estimated. The new signal processing circuits were simulated in relation to the results of complex electro mechanical diaphragm and SPICE energy harvesting power source simulation.
