In total, there are four piezoelectric coefficients, dij, eij, gij, and hij defined as follows: where the first set of four terms corresponds to the direct piezoelectric effect and the second set of four …

The piezoelectric coefficient is the same for both the direct and converse piezoelectric effect at the same magnitude of either electric field and induced strain or mechanical stress and induced …

Piezoelectric coefficients – these properties describe the amount of charge that is generated when a force is applied to a piezoelectric material. From: Ceramic Thick Films for MEMS and …

There are 4 mathematically-equivalent forms of piezoelectric constitutive rela-tions, each one involves one of 4 different third-order tensors of piezoelectric coupling coefficients – see Table …

The principal piezoelectric coefficient, d, relates polarization, P, to stress, X, in the direct effect (P = dX) and strain, x, to electric field E (x = dE). Thus the units of d are [C/N] or [m/V] which are …
