Piezoelectric ceramics is an information functional ceramic material that can convert mechanical energy and electrical energy into each other – piezoelectric effect. Piezoelectric ceramics have not only piezoelectric properties, but also dielectric properties, elasticity, etc. They have been widely used in medical imaging, acoustic sensors, acoustic transducers, ultrasonic motors, etc. Piezoelectric ceramics are made by using their materials to cause the relative displacement of the internal positive and negative charge centers under the action of mechanical stress, resulting in the polarization, resulting in the appearance of binding charges with opposite signs on the surfaces of both ends of the materials, namely piezoelectric effect, which has sensitive characteristics. Piezoelectric ceramics are mainly used to manufacture ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic frequency discriminators, high-voltage generators, infrared detectors In addition to being used in high-tech fields, SAW devices, electro-optic devices, ignition and detonation, piezoelectric gyroscopes, etc., are more used to serve people in daily life and make efforts to create a better life for people.
