An equivalent circuit model for the unloaded piezoelectric vibrator in the thickness mode is presented. The model contains two branches, the motional branch and the static branch, like the lossless resonator model, but the circuit elements are genera

We present a technique to measure the piezoelectric strain (charge) coefficient using an optical lever technique. The optical lever consists of a laser source, a levered mirror connected to the sample and a linear CCD array detector (pixel size = 13

Piezoelectric 0–3 ceramic-glass composites have been developed by firing a mixture of modified Lead Zirconate Titanate (PZT) and a lead based glass powder. Composites with 58 to 92 volume percent PZT were fabricated and their dielectric, piezoelect

We describe a new method for determining the real and imaginary parts of the material constants of piezoelectric resonators. Our method is applicable to any of the common resonator geometries, it is non-iterative and its accuracy is comparable to tha

We describe a new piezoelectric hydrophone material, a 1-3 type Lead Zirconate Titanate (PZT)-Air composite, which is constructed in such a way that the PZT rods are isolated from stresses in the 1 and 2 directions. The theory for these new composite
