MEMS microphones in general and automotive – a tutorial Just as the semiconductor content in cars is increasing, so do MEMS microphones play an increasing role – both technology and application driven. Technology driven, because the legacy Electret Condenser Microphones are giving way to leveraging the benefits of MEMS technology, in automotive as they have in consumer electronics. Application driven because MEMS microphones play an increasing role in driver and passenger comfort, safety and the way we interact with our cars. This tutorial aims to give a broad overview of MEMS microphones with a particular focus on automotive. The participants will walk away knowing about MEMS microphone technology, its capabilities and (current) limits and applications in vehicles.
