Piezoelectric coefficient

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 $d_{ij}$; see Piezoelectricity § Mechanism for further details.
