Aluminum Nitride-based Piezoelectric MEMS Resonators and Acoustic Sensors

Thin-film piezoelectric materials are gaining increasing importance in the MEMS industry. They offer opportunity to integrate thin film deposition in a MEMS or CMOS process. Aluminum nitride (AlN) is one of the most promising materials among the commonly used piezoelectric thin films. AlN-based bulk acoustic wave filters have demonstrated great commercial success. It has shown great potentials in the applications, from microphones to piezoelectric micromachined ultrasound transducers (PMUT), as well as thin film-based imaging device.

This talk briefly introduces the research activities on AlN-based piezoelectric MEMS resonators and acoustic sensors in our group at Wuhan University.
