摘要：
The hydrostatic piezoelectric coefficient dh of Pb(ZrxTi1 − x)O3 ceramics (PZT), and of Pb(Zn1/3Nb2/ 3)O3-PbTiO3 and Pb(Yb1/2Nb1/2)O3-PbTiO3 (PZN-PT, PYN-PT, respectively) single crystals with compositions near to the morphotropic phase boundary (MPB) have been measured using a dynamic hydrostatic method. The effects of DC electric field and static component of hydrostatic stress on dh of PZT ceramics, PZN-PT and PYN-PT single crystals were studied. Changes of the piezoelectric hydrostatic coefficients dh caused by an electric field (DC bias) were observed along with pressure and temperature dependencies. The measurement of the hydrostatic piezoelectric coefficient dh seems to be promising for investigation of intrinsic (single domain) and extrinsic (domain-walls) contributions to piezoelectric behavior of single crystals and ceramic materials.
