The bipolar fatigue behaviors of lead magnesium niobate-lead zirconate titanate (PMN-PZT)
ceramics sintered by conventional sintering (CS) and spark plasma sintering (SPS) were …

Fatigue degradation is a significant problem in piezo/ferroelectric materials and their
commercial applications. The major causes of electrical fatigue degradation are a domain …

The bipolar fatigue behavior for Mn-doped PZN-PNN-PZT ceramics with composition near
the MPB region was investigated at both 0.6 Ec and 2 Ec (where Ec is a coercive field). It …

We investigate the fatigue behavior of bulk polycrystalline lead zirconate titanate (PZT)
during bipolar electric field cycling. We characterize the frequency-and cycle-dependent …

Relaxor ferroelectrics are the most promising materials for dielectric capacitors because of
their rapid charge/discharge capability and outstanding thermal stability. However, to satisfy …

The deformation of crack tip in PZT ceramics under cyclic electric field loading was
characterized by Digital Image Correlation (DIC) technique. Two other specimens without …

The fatigue behaviour of a piezoelectric ceramic stack co-fired at low temperatures under the
influence of a large cyclic dynamic load was studied. The piezoelectric ceramic stack is …

Several mechanisms and methods have been proposed to study the nature of electric
fatigue in ferroelectric materials with perovskite structure, including defect agglomeration …

Abstract Domain switching in ferroelectrics is at the heart of many functionalities, and the
visualization of switching pathway is the key to understand the fundamental properties and …

This chapter starts with a brief introduction on ferroelectric materials, actuators and their role
and importance in inkjet printers. Thereafter, the problem of piezoelectric actuators, which is …
