Piezoelectric ceramics have a variety of different principles in the conversion process. From the current situation, the piezoelectric ceramics are basically converted effectively through the action of sound waves, and the actual conversion of these piezoelectric ceramics In the process, it will be able to generate more inductive loads, and can even be converted by the piezoelectric effect of piezoelectric ceramics. In the actual conversion, it can also generate more vibrations, and there will be more acoustic waves. Of course Among them, the conversion of the entire piezoelectric ceramics also has different conversion work, and there will be more standards for use.

Piezoelectric ceramic sheet is a kind of electroacoustic device with simple structure and light weight. It has the advantages of high sensitivity, no magnetic field spreading, no copper wire and magnet, low cost, low power consumption, convenient repair, and convenient mass production. widely used. Suitable for the transmission and reception of ultrasonic and infrasonic waves. Piezoelectric ceramic sheets with a relatively large area can also be used to detect pressure and vibration. The working principle is to use the reversibility of the piezoelectric effect. Applying audio voltage on it can generate mechanical vibration, thereby makes a sound. If pressure is continuously applied to the piezoelectric ceramic sheet, it will also generate voltage and current.
Common piezoelectric ceramics
1. Barium titanate (BaTiO3) piezoelectric ceramics have high piezoelectric coefficient and dielectric constant, and their mechanical strength is not as good as quartz.
2. Lead magnesium niobate Pb(MgNb)O3-PbTiO3-PbZrO3 piezoelectric ceramics (PMN) have a high piezoelectric coefficient and can continue to work under pressures as high as 700kg/cm2, and can be used as a force sensor at high temperatures.
3. Lead zirconate titanate Pb (Zr•Ti) O3 piezoelectric ceramics (PZT) have high piezoelectric coefficients, and various electromechanical parameters change little with external conditions such as temperature and time. Add one or two to lead zirconate titanate Kind of trace elements, PZT materials with different properties can be obtained.

PiezoelectricCeramics (PZT) materials are categorized as functional ceramics. In sensors they make it possible toconvert forces, pressures and accelerations into electrical signals, and in sonic and ultrasonic transducers and actuators they convert electric voltages into vibrations or deformations.PiezoelectricCeramics materials are classified according to their chemical composition on the one hand, and by the specific application conditions on the other.
