At the 2022 IEEE International Ultrasonics Symposium, imec presents a piezoelectric Micromachined Ultrasound Transducer (pMUT) array that is compatible with flat-panel-displays (FPD) process technologies. The array demonstrates acoustic pressures in mid-air above 1kPa, a pressure level relevant for enabling mid-air haptics and directed sound. Moving from wafer-based to FPD-compatible processes prepares the pMUT technology for the integration of future mid-air applications, such as vibro-hapti...
