The longitudinal piezoelectric effect induced by a direct current bias field was investigated in PMN:PT family of relaxor ferroelectric ceramics in the frequency range from 0.1 Hz to 50 kHz. The piezoelectric $d_{33}$ coefficient was studied by measuring the strain induced by the applied electric field. Under the 10 kHz driving field, the large piezoelectric strain coefficient, $d_{33}$, of 800 pC/N is obtained. The piezoelectric strain coefficient related dielectric and electrostrictive parameters were also studied under direct current bias and the $d_{33}$ coefficient was calculated by the equation $d_{33}{=}2Q_{11}P_{3}\varepsilon_{33}$. The results are in good agreement with the directly measured ones. The dispersion of the piezoelectric effect is mainly due to the dielectric dispersion.
