dc.description.abstractPiezoelectric ceramics are used in biomedical, naval, micromechanical, and many other precision engineering applications and therefore require a well-characterized, stable response. Utilizing a new capability developed on the The Australian Strain Scanner (TASS) at ANSTO, we have directly measured in situ the intrinsic and extrinsic t contributions to the piezoelectric effect in soft lead zirconate titanate (PZT) ceramics. The 002 and 200 diffraction peaks are measured as a function of time using a stroboscopic technique which enables timing resolutions of less than 30us. In other words, we have measured the 200 and 002 peak profiles as a function of time during piezoelectric activation. In this tetragonal crystal structure, a comparison of the 002 and 200 integrated intensity yields the non-180° domain switching contribution (extrinsic) while shifting of the peaks yields the change in 001 and 100 lattice strains (intrinsic). Both components lead to the macroscopic strain measured as the piezoelectric response, which is found to be a function of frequency and applied electric field. These results go toward explaining the nonlinearities of piezoelectric response versus frequency and magnitude of driving field measured in earlier work. © The Authorsen_AU
