Piezoelectric ring crystal PZT Material

Ring piezoelectric ceramics make use of the characteristics of piezoelectric ceramics to convert external force into electrical energy, which can produce piezoelectric igniter, mobile X-ray power supply, projectile detonation device. Using two piezoelectric ceramic pillars 3 mm in diameter and 5 mm in height instead of ordinary flint, a gas electronic lighter can be made that can be continuously lighted tens of thousands of times. Using piezoelectric ceramics to convert electrical energy into ultrasonic vibration can be used to explore the position and shape of underwater fish, non-destructive metal detection, ultrasonic cleaning, ultrasonic medical treatment, can also be made into a variety of ultrasonic cutters, welding devices and soldering iron, plastic and even metal processing.

 

The piezoelectric ceramics are sensitive to external forces so that they can even sense the air disturbance caused by flying insects'flapping wings more than a dozen meters away and convert extremely weak mechanical vibrations into electrical signals. This characteristic of piezoelectric ceramics can be used in sonar system, weather detection, telemetry environmental protection, household appliances and so on.

 

Submarine diving into the deep sea is equipped with sonar systems called underwater scouts. It is an indispensable equipment for underwater navigation, communication, reconnaissance of enemy ships, sweeping enemy mine laying, and a powerful tool for developing marine resources. It can detect fish swarms, explore seabed topography and landforms. In this sonar system, there are a pair of bright "eyes" - piezoelectric ceramic underwater transducer. When the acoustic signal emitted by the underwater acoustic transducer touches a target, it will produce a reflection signal. The reflection signal is received by another receiving underwater acoustic transducer, and then the target is found. At present, piezoelectric ceramics are one of the better materials for making underwater acoustic transducers.
