摘要：

We have measured the piezoelectric coefficients of PZT ceramics by resonance and laser interferometry methods. The surface displacement was measured by a single-beam Michelson interferometer. A stable double-beam interferometer was also used to suppress the effect of bending. The piezoelectric coefficients d(ij) of the PZT ceramic and of the 0-3 ceramic-polymer composites were determined from the displacements. The results for PZT d(ij) coefficients obtained by the both methods are in good agreement. (C) 2001 Elsevier Science Ltd. All rights reserved.
