At the 2022 IEEE International Ultrasonics Symposium, imec, a world-leading research and innovation center in nanoelectronics and digital technologies, presented 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.…
