The piezoelectric effect is understood as the linear electromechanical interaction between mechanical and electrical condition in crystalline materials without inversion symmetry. [4] the piezo-electric effect is a reversible process in that materials exhibiting the direct piezoelectric effect (the generation internal electrical charge resulting from an applied mechanical force) are also opposite the piezoelectric effect (the internal generation of mechanical stress resulting from an applied electric field).
