The Analysis of Degradation Phenomena in Piezoelectric Ceramics by Equivalent Circuit Analysis Method

ABSTRACT

The analysis of degradation phenomena of poled PZT ceramics was investigated relate to piezoelectric equivalent circuit elements. As a result, in the case of impressed mechanical shock on poled specimen of degradation phenomena was explained by domain rearrangement, and in the case of left in air, degradation phenomena was explained by space charge diffusion.
