Abstract: In this paper, air-coupled piezoelectric micromachined ultrasonic transducers (PMUTs) using 36% scandiumdoped aluminum nitride (ScAlN) thin-film are presented. ScAlN is known to exhibit ...
Abstract: Piezoelectric Micromachined Ultrasonic Transducers (PMUT) and Capacitive Micromachined Ultrasonic Transducers (CMUT) have seen great developments in recent years, both in terms of ...
