Piezoelectric ultrasonic transducers play a critical role in modern sensing and actuation by converting electrical signals into high‐frequency mechanical vibrations and vice versa. Recent advances ...

Piezoelectric transducers are commonin ultrasonic and acoustic-alarm-signaling applications. To getenough acoustic power from a piezoelectrictransducer, you must power thedevice with a frequency at or ...

Ultrasound refers to any audio signal above the range of human hearing. Generally that’s accepted as 20 kHz and up. Unlike electromagnetic signals, ultrasonics are still operating in a medium – ...
