This design shows how a piezoelectric transducer's acoustic output can be increased while minimizing the parts count and cost.

The piezoelectric diaphragm, or bender plate, comprises a piezoelectric ceramic plate, with electrodes on both sides, attached to a metal plate made of brass, stainless steel, or a similar material ...

Piezoelectric ultrasonic transducers transmit and receive ultrasonic waves used in sensing and imaging applications. These devices possess the properties of both sensors and actuators.

Some cool-mist humidifiers work by flinging water at a vaporizer, but our favorite kind uses a piezoelectric transducer. These work by using high-frequency sound waves to pound the surface of the ...
