Definition

The reversible coupling in certain non‑centrosymmetric crystalline or properly poled polycrystalline materials between mechanical stress/strain and electrical charge or electric field: mechanical deformation generates an electric charge (direct piezoelectric effect) and an applied electric field produces mechanical strain (converse piezoelectric effect).
