Micromachined ultrasonic transducers and acoustic sensors based on piezoelectric thin films
A review is given on the current state of the art in piezoelectric micromachined ultrasonic transducers (pMUT). It is attempted to quantify the limits of pMUT's with respect to the electromechanical coupling, and to relate current achievements. Main needs for future research are identified in design, micromachining and further improvements of PZT films. Applications are shortly reviewed.
