    Piezoelectric effect of piezoelectric ceramics

    When the piezoelectric ceramic is polarized, there is a strong residual field polarization inside the ceramic material. When the ceramic material is subjected to an external force, the boundary of the domain moves is causing a change in the polarization intensity and resulting a piezoelectric effect
