Abstract:
1. An implantable electromechanical converter for receiving oscillations from an ear ossicle and for converting the received oscillations into an electrical voltage, for use as a microphone for a cochlea implant or an implantable hearing aid, comprising: a hermetically sealed hollow body made of a biocompatible material, said hollow body having a thin shell with an exterior side adapted to be coupled to the ear ossicle and an interior side; an electronic circuit for conditioning the electrical voltage located inside the hollow body, and a stable edge supporting the thin shell, said stable edge being coupled to a counter-support in the middle ear space, wherein the electromechanical converter is implemented as at least one piezoelectric converter element housed in the hollow body and coupled the interior side of the thin shell.
