Piezoelectric Moduli of Piezoelectric Ceramics

Journal of the American Ceramic Society, 1996
The effective piezoelectric moduli of polycrystalline piezoelectric ceramics are calculated using a straightforward averaging method (a Voigt average) and a more rigorous effective‐medium theory recently developed for piezocomposites. The effects of polarization orientation within each crystallographic domain and the shape of the domain on the ...

Disc Piezoelectric Ceramic Transformers

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2012
In this contribution, we present our study on disc-shaped and homogeneously poled piezoelectric ceramic transformers working in planar-extensional vibration modes. Transformers are designed with electrodes divided into wedge, axisymmetrical ring-dot, moonie, smile, or yin-yang segments.

Piezoelectric Ceramics

Journal of the American Ceramic Society, 1958
The discovery of piezoelectric effects in electrically poled barium titanate ceramic, in the early l940, was a revolutionary contribution to the electromechanical transducer art. Since then, improved barium titanate ceramics adapted to a variety of practical needs have been developed, and a number of new piezoelectric oxide‐type compounds have been ...
