Abstract

Images of the piezoresponses (PRs) in the frequency range of 15–2500 kHz are obtained for dense polarized PCR-1 piezoceramics. It is shown that in the region of resonance, the dependence of PR amplitudes on frequency includes a function that changes its sign at the resonance frequency. Possible reasons for the inversion of PR contrast in the narrow range of frequencies near 725 kHz are discussed.
