The piezoelectric coefficient or piezoelectric modulus, usually written d33, quantifies the volume change when a piezoelectric material is subject to an electric field, or the polarization on the application of stress. In general, piezoelectricity is described by a tensor of coefficients d i j {\displaystyle d_{ij}} ; see Piezoelectricity § Mechanism for further details.
