Tunable Ultrasound Transducers

Broadening market applications for ultrasound transducers

Technology Overview

Piezoelectric micromachined ultrasound transducers (PMUTs) have emerged as a substitute to conventional ultrasonic sensors. A typical PMUT is a suspended membrane clamped at its edges and driven through piezoelectric effect by the application of an AC voltage. The tunable ultrasound transducers developed provided a range of operating frequencies that cannot be optimally addressed by a single transducer.
