Abstract

A PMUT device includes a membrane element adapted to generate and receive ultrasonic waves by oscillating, about an equilibrium position, at a corresponding resonance frequency. A piezoelectric element is located over the membrane element along a first direction and configured to cause the membrane element to oscillate when electric signals are applied to the piezoelectric element, and generate electric signals in response to oscillations of the membrane element. A damper is configured to reduce free oscillations of the membrane element, and the damper includes a damper cavity surrounding the membrane element, and a polymeric member having at least a portion over the damper cavity along the first direction.
