An implantable microphone for use in hearing systems includes a housing having a sidewall, a first membrane coupled to a top portion of the housing and configured to move in response to movement from an auditory ossicle, and a second membrane coupled to the sidewall such that an interior volume of the housing is divided into a first volume and a second volume. The first volume has an opening that permits fluid to flow out from the first volume. The implantable microphone also includes a vibration sensor coupled to the second membrane and configured to measure the movement of the second membrane and to convert the measurement into an electrical signal. The vibration sensor may include a piezoelectric sensor and/or a MEMS sensor.

Implantable microphone for hearing systems

An implantable microphone for use in hearing systems includes a housing having a back wall. The back wall has a recess (e.g., blind hole) configured to be coupled to an auditory ossicle. The implantable microphone also includes a membrane coupled to a top portion of the housing and a vibration sensor adjacent to the membrane. The membrane is configured to move in response to movement from the auditory ossicle, and the vibration sensor is configured to measure the movement of the membrane and to convert the measurement into an electrical signal.
