The crystal grains inside piezoelectric ceramics have many spontaneously polarized electric domains, and they have a certain polarization direction. When there is no external electric field, the electric domains are randomly distributed in the crystal, and their polarization effects are canceled out

Piezoelectric transducers are ultrasonic sensors made by using the piezoelectric effect produced by certain dielectrics. The so-called piezoelectric effect refers to the phenomenon that when certain dielectrics undergo deformation (including bending and stretching deformation) due to the polarizatio

Transducing materials and acoustic materials:PZT piezoelectric ceramics are developing towards industrialization. So far, lead zirconate titanate (PZT) piezoelectric ceramics have been used as water.The transducer material of the acoustic transducer still dominates. PZT piezoelectric ceramics develo
