Abstract: For the first time, we develop piezoelectric micromachined ultrasound transducer (PMUT) array with the cells having suspended vibrational membranes and the array having the same-dimension ...

Abstract: This paper presents a multi-element self-focusing piezoelectric micromachined ultrasound transducer (ms-fPMUT) for multi-frequency ultrasound stimulation across bio-tissues. This transducer ...
