Abstract: In this work, a piezoelectric-capacitive hybrid micromachined ultrasonic transducer (HMUT) with a high round-trip gain was developed to achieve superior pulse-echo imaging performance.

Abstract: The flexural ultrasonic transducer (FUT) is a sensor primarily composed of a circular metallic plate, to which a piezoelectric ceramic disc is bonded. The vibrations generated from the ...

Not so, if you use a pair of specialised ultrasonic transducer arrays to move the air instead! (Video, embedded below) Three banks of thrusters provide a 180 degree steerable net force Details are ...
