piezoelectric ceramic ring

The bound charges will appear at both ends of the polarized piezoelectric ceramics, so a layer of free charges from outside will be adsorbed on the surface of the electrodes. When an external pressure F is applied to the ceramic sheet, discharges will occur at both ends of the sheet. On the contrary, charging will occur when tension is applied. This phenomenon of mechanical effect transforming into electrical effect belongs to the positive piezoelectric effect.

 

In addition, piezoelectric ceramics have the property of spontaneous polarization, and spontaneous polarization can change under the action of external electric field. Therefore, when an external electric field is applied to a piezoelectric dielectric, the change as shown in the figure will occur, and the piezoelectric ceramics will be deformed. However, the deformation of piezoelectric ceramics is due to the increase of polarization intensity when the same external electric field as spontaneous polarization is added. The increase of polarization intensity makes the piezoelectric ceramic sheet elongate along the polarization direction. On the contrary, if the reverse electric field is applied, the ceramic sheet will be shortened along the polarization direction. This phenomenon, which is transformed from electrical effect to mechanical effect, is the inverse piezoelectric effect.
