A method for measuring the spatial variation of the macroscopic poling state of a piezoelectric material using an ultrasonic transducer is described. The relatively simple method clearly indicates the distribution of poling within the material, demonstrated by the testing of a collection of partially poled lead zirconate titanate samples. © 2001 American Institute of Physics.

    Studies on magnetoelectric (ME) coupling in a semiring of lead zirconate titanate (PZT) with a Terfenol-D insert reveal strong ME coupling at low frequencies and two orders of magnitude enhancement in the strength at resonance associated with a unique bending mode in PZT. A model is discussed...

    We have investigated piezoelectric lead zirconate titanate (PZT)-stainless steel cantilevers as real-time in-water cell detectors using yeast cells as a model system. Earlier studies have shown that mass changes of a cantilever can be detected by monitoring the resonance frequency shift. In this...

    Bipolar fatigue in ferroelectric lead-zirconate-titanate was previously shown to induce stable pinning centers for ferroelectric domain walls resulting in a significant loss in switchable polarization, but only fairly weak offsets were induced. The corresponding scenario after unipolar fatigue...
