A technique for testing a piezoelectric microactuator of a read/write head of hard disk drive (HDD) is described. The proposed technique is based on the measurement of an equivalent capacitance of the PZT thin-film ceramic. It exploits the temperature dependent characteristic of the PZT. By carefully heating the PZT element while measuring its capacitance,(More)
Fatigue behaviors of Lead Zirconate Titanate (PZT) ceramics under different amplitude of bipolar electrical loads have been investigated. Fatigue behavior is represented by the change of hysteresis loops and remnant polarization. Three levels of electrical load amplitudes (1.00, 1.25 and 1.50 kV /mm) were applied in this experimental. It was found that the(More)
