Summary :

Actuator operation in a liquid is described using vibration motion on the side surface of a cylindrical piezoelectric vibrator. A foam urethan layer is indispensable for the suppression of the acoustic energy radiation into the liquid. An ultrasonic motor in water is demonstrated successfully.
