Inverse piezoelectric effect
Inverse piezoelectric refers to the phenomenon that the application of an alternating electric field to the crystal causes mechanical deformation of the crystal. Transmitters made with the inverse piezoelectric effect can be used in electroacoustic and ultrasonic engineering. There are five basic forms of force deformation of piezoelectric sensitive components: thickness deformation type, length deformation type, volume deformation type, thickness shear type, and plane shear type. Piezoelectric crystals are anisotropic, and not all crystals can produce piezoelectric effects in these five states. For example, quartz crystal does not have the piezoelectric effect of volume deformation, but has good piezoelectric effect of thickness deformation and length deformation.
