piezoelectric effect otherwise piezoeffect (rus. пьезоэффект) — reversible electromechanical coupling of the electric polarisation and mechanical deformation in anisotropic dielectric media with certain crystal structure and symmetry.


The direct piezoelectric effect, when an electric charge is induced on the surface of a crystal when a mechanical stress is applied, must be distinguished from the reverse piezoelectric effect, when the deformation of a crystal occurs when it is espoused in an external electric field.
