Piezoelectric Ceramic Rectangular Element PZT material

The piezoelectric ceramic material is between pzt8 and PZT5. It has high sensitivity and low dielectric loss. It is suitable for dual-purpose transducer with low transmitting power and receiving function at the same time. At present, the ultrasonic atomization transducer produced by the piezoelectric ceramic material has been put into production in batch.
 

Piezoelectric ceramics, also known as transducer, is an indispensable and important part in the field of modern electronic technology. Piezoelectric ceramics are widely used in modern communication, radar, sonar, automatic measurement and control, ultrasonic energy conversion, ignition and ignition, ultrasonic sterilization, ultrasonic power and so on. At present, the development of piezoelectric ceramic materials and their applications in China is still in the development stage, and the development of this industry will have broad prospects.

When the voltage acts on the piezoelectric ceramic, it will produce mechanical deformation with the change of voltage and frequency. On the other hand, when a piezoelectric ceramic is vibrated, an electric charge is generated. Using this principle, when an electric signal is applied to the vibrator composed of two piezoelectric ceramics or one piezoelectric ceramic and one metal sheet, so-called double piezoelectric chip element, ultrasonic waves will be emitted due to bending vibration. On the contrary, when ultrasonic vibration is applied to the dual piezoelectric wafer element, an electrical signal is generated. Based on the above functions, piezoelectric ceramics can be used as ultrasonic sensors.
