Figure 5: Typical waveforms of stress-induced voltage produced single crystal and ceramic specimens during depolarization in the high voltage mode.

(a) PIN-PMN-PT single crystal specimen. (b,c) PZT 52/48 and PZT 95/5 ceramic specimens, respectively. The voltage started rising at the moment of time when the compression front entered the front face of the specimens. The voltage increased to its maximum during a few hundred of nanoseconds and then decreased due to an internal breakdown within the specimen. The experimental results indicate that the peak voltage was achieved when only a part of the ferroelectric specimens was depolarized under stress. This is typical for ferroelectric specimens of different shape and sizes.
