Disc Piezoelectric Ceramic Made of PZT4

Product Description

Piezoelectric devices make use of the piezoelectric effect to perform a function. The piezoelectric effect is found on some crystals, which acquire a charge when compressed, twisted or distorted. This provides a convenient transducer effect between electrical and mechanical oscillations.
Piezoelectric transducer has broad application in ultrasonic beauty machine because of ultrasonic's heat effect, engine vibration effect and penetrability effect.
