{wiki=Electrostriction}
Electrostriction is a phenomenon observed in certain materials, particularly dielectrics and ferroelectrics, where the material undergoes a mechanical deformation in response to an applied electric field. Unlike piezoelectricity, which produces a charge separation in response to stress, electrostriction is a more general effect that occurs in any dielectric material subjected to an electric field.
