Product Description
Piezoelectric ceramics is a kind of information functional ceramic material piezoelectric effect, which can convert mechanical energy and electrical energy into each other. Piezoelectric ceramics not only have piezoelectric, but also have dielectric and elasticity. They have been widely used in medical imaging, acoustic sensors, acoustic transducers, ultrasonic motors and so on. Piezoelectric ceramics are made by using the relative displacement of internal positive and negative charge centers caused by mechanical stress, resulting in binding charges with opposite symbols on the surfaces of both ends of the material, that is, piezoelectric effect. Piezoelectric ceramics are mainly used to manufacture ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers Ceramic frequency discriminator, high voltage generator, infrared detector, surface acoustic wave device, electro-optic devicepiezoelectric gyroscope are not only used in high-tech field, but also serve people in daily life and strive to create a better life for people.
