Abstract

Special care must be taken in measuring the acoustic emission (AE) in piezoelectric ceramics, because a self vibration of the ceramics is caused by a power supply through a feedback system. Significantly different data from the results previously reported were obtained by eliminating the self vibration of the ceramics. The dynamic contribution of 180° and non-180° domain reorientation on the AE generation were discussed on the basis of AE data observed in lead zirconate-titanate (PZT) ceramics.
