Piezoelectric Ceramic Resonators

Part of the book series: Topics in Mining, Metallurgy and Materials Engineering ((TMMME))

Abstract

Piezoelectric ceramic resonators with divided electrode used for the piezoelectric transformation are reviewed in details for various resonator shapes, electrode pattern, poling direction, bulk and multilayer geometry. Piezoelectric transformers of bar, plate, disc, and ring shapes are analytically modeled by the immittance method for one-dimensional vibration modes as a function of dimensions, material properties of ceramics, frequency, and impedance load. Numerical examples of transformer parameter calculation including electrode pattern optimization are presented. Comprehensive list of literature references on piezoelectric transformers is given.
