Abstract
The different forms of the linear piezoelectric equations of state obtained from the various combinations of the two elastic (stress, strain) with the three electric quantities (field, displacement and polarization) are given in a table. In order to show the similarities of the various piezoelectric constants more clearly, the three groups of piezoelectric moduli (piezoelectric stress constants) usually expressed as e, h, a are denoted respectively by eE, eD, eP and the piezoelectric coefficients (piezoelectric strain constants) d, g, b are expressed by dE, dD, dP. The superscripts refer to the electric quantity, E, D or P, held constant for the direct piezoelectric effect or to the applied electric quantity for the converse effect.
