Piezoelectric Acoustic Emission Sensor

Piezoelectric ceramics is one of electronic ceramics. When a piezoelectric ceramic is hit, a high voltage is generated instantaneously, and conversely, when a voltage is applied, the piezoelectric ceramic expands and contracts. Piezoelectric ceramics are ceramics that have the function of converting electrical energy and mechanical energy.
Fuji Ceramics offers elements suitable for various applications while selecting a wide range of materials for piezoelectric ceramics through consistent processes from research and development to manufacturing.
The application fields of piezoelectric ceramics can be broadly divided into vibrators and transducers. Vibrators are used for electrical input – mechanical vibration – electrical output, and include ceramic oscillators, filters, piezoelectric buzzers, and piezoelectric transformers. Transducers include ultrasonic cleaners and actuators that use electrical input-mechanical output, and vibration/shock sensors and piezoelectric elements that use mechanical input-electrical output. There are a wide range of application fields that have been put into practical use.
