Piezo Ceramics

Piezo-ceramics are used to convert mechanical parameters, such as pressure and acceleration to electrical parameters or conversely to convert electrical signals to mechanical movement or vibration. In sensors they make it possible to convert forces, pressures and accelerations into electrical signals, and in ultrasonic transducers and actuators they convert electric voltages into vibrations or deformations. Piezo-ceramics have a wide range of uses in different industries and even daily life. Applications include ultrasonic distance sensors, flow rate measurement, ultrasonic cleaning, drilling and welding, ultrasonic machining, household gas lighters, kids shoes with lights, burglar alarm sensors, nebulizers for medicine and cosmetic application, pneumatic/hydraulic valves, sound emitters, ultrasonic nebulizers, knock sensors, and back-up sensors.
