Ring Piezo ceramic
Piezoelectric ceramics convert the external force into electrical energy and can produce piezoelectric igniters, mobile X-ray power sources, bomb detonation devices, and gas electronic lighters.Piezoelectric ceramics convert electrical energy into ultrasonic vibration, which can be used in ultrasonic cleaning, ultrasonic medical treatment, and can be made into various ultrasonic cutters, welding devices, and soldering irons to process plastics and even metals.
Piezoceramics have high sensitivity to external forces ，it can sense the air disturbance caused by flying insects beating their wings more than ten meters away, and convert extremely weak mechanical vibrations into electrical signals, which can be applied to sonar systems, meteorological detection and telemetry, and the environment. Protection, household appliances, etc.
On the Submarine that dive into the deep sea, equipped with the sonar systems which people called underwater scouts. It is an indispensable equipment for underwater navigation, communications, reconnaissance of enemy ships, sweeping enemy mines, and a powerful tool for the development of marine resources. It can detect fish and explore the topography of the sea floor. In this type of sonar system, there is a pair of bright "eyes" - piezoelectric ceramic underwater acoustic transducer. When the sound signal emitted by the underwater acoustic transducer hits a target, a reflection signal is generated. This reflection signal is received by another receiving underwater acoustic transducer, and the target is found. At present, piezoelectric ceramics is one of the better materials for producing underwater acoustic transducers.
