Abstract

See full text

Disclosed examples generally include methods and apparatuses related to microphone units, such as may be found in implantable medical devices (e.g., cochlear implants). Microphone units generally include a microphone element connected to a chamber having a concave floor with the chamber covered by a membrane. Microphone units can be configured to produce an output based on pressure waves (e.g., sound waves) that reach the membrane. In an example, a microphone unit has a pressurized gas within the chamber below the membrane such that, while in a static state, the membrane deflects away from the chamber floor.
