Piezoelectric ring ceramic ultrasonic piezoelectric ceramic piezo disc piezoelectric ceramic vibration sensor

In industry, geological detectors contain piezoelectric ceramic components that can be used to determine the geological conditions of the strata and identify underground mineral deposits. There is also a voltage ceramic transformer in TV sets, which reduces its size and weight, with an efficiency of up to 60% to 80%. It can withstand 30000 volts of high voltage and maintain stability, completely eliminating the defect of blurring and deformation of TV images. Install a piezoelectric ceramic buzzer in the belly of a toy puppy, and the toy will emit realistic and interesting sounds. Application in automobiles: Install a simple piezoelectric ceramic actuator in the brake piston of the car, apply a “shaking” frequency to the support plate of the internal brake block, effectively suppress the vibration that generates sharp noise, and thus play a role in temperature and humidity changes and normal wear and tear of the brake system. Piezoelectric ceramics can also be used as piezoelectric ceramic knock sensors, ultrasonic sensors, acceleration sensors, and other categories in automobiles. The application of piezoelectric ceramics in fuel injectors of automotive fuel systems is currently at the forefront of development.
