L. Burianova et al., Determination of the piezoelectric coefficients d(ij) of PZT ceramics and composites by laser interferometry, J EUR CERAM, 21(10-11), 2001, pp. 1387-1390
We have measured the piezoelectric coefficients of PZT ceramics by resonanc
e and laser interferometry methods. The surface displacement was measured b
y a single-beam Michelson interferometer. A stable double-beam interferomet
er was also used to suppress the effect of bending. The piezoelectric coeff
icients 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) coefficie
nts obtained by the both methods are in good agreement. (C) 2001 Elsevier S
