Mr Matt Crowley, CEO – Vesper Technologies | Topic: Piezoelectric MEMS – Unique Technology for Audio Sensing
Vesper has pioneered the commercialization of piezoelectric MEMS microphones. These microphones have several beneficial characteristics such as 1) they are highly resistant to environmental contaminants such as dust, water, particles and oil. 2) they enable ZeroPower Listening which greatly extends the battery life in always listening systems. Specific use cases for ZeroPower Listening will be discussed and customers disclosed. This presentation will explain these advantages and highlight specific use cases and applications for piezoelectric MEMS microphones. I will also compare piezoelectric MEMS microphones with the incumbent capacitive MEMS technology and older ECM technology. Some of the development challenges overcome to bring piezoelectric MEMS microphones to volume production will also be reviewed.
