what is the use of piezoelectric sensor

Piezoelectric transducers use the piezoelectric effect and inverse piezoelectric effect of piezoelectric ceramics to realize the mutual conversion of electrical energy and acoustic energy. Piezoelectric ultrasonic transducers are one of them. Piezo ceramic platesare underwater devices that emit and receive ultrasonic waves underwater. It is acoustic devices. Piezo ceramic generators transducers in the underwater to receive action of sound waves, which charges are induced at both ends of the transducer. This is the sound wave receiver; if an alternating electric field of piezoelectric sensor buy is applied to the piezoelectric ceramic wafer, the piezo ceramic wafer will thinning and thickening from time to time, it generates vibrations and emits acoustic waves. This is the ultrasonic transmitter. piezoelectric ring crystal are also widely used in industry as underwater navigation, ocean detection, precision measurement, ultrasonic cleaning, solid flaw detection, and medical imaging,ultrasonic diagnosis, ultrasonic disease treatment and other aspects. Another area of application of 1.7 MHz piezoelectric ringtoday is telemetry and remote control systems. Specific application examples include piezoelectric ceramic buzzers, piezoelectric igniters, and ultrasonic microscopes.
