  • Piezoelectric ceramics is an information-functional ceramic material that can convert mechanical energy and electrical energy into each other - piezoelectric effect. In addition to piezoelectricity, piezoelectric ceramics also have dielectric properties, elasticity, etc., and piezo ceramic and piezo ceramic rings have been widely used in medical imaging, Acoustic sensors, acoustic transducers, ultrasonic motors, etc. Piezoelectric ceramics are made by using the material under the action of mechanical stress to cause the relative displacement of the internal positive and negative charge centers to cause polarization, resulting in the appearance of bound charges with opposite signs on the surfaces of the material, that is, the piezoelectric effect. Ceramics are mainly used in the manufacture of ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic frequency discriminators, high voltage generators, infrared detectors, surface acoustic wave devices, electro-optical devices, In addition to being used in high-tech fields, such as ignition and detonation and piezoelectric gyroscopes, it is more about serving people in daily life and working hard for people to create a better
