It is only in the last few years that multilayer transducers have been prepared by tape casting. Owing in part to the large body of information that is available from the multilayer capacity industry and recent work in the field of rheology, great strides have been made in this area. It is shown that multilayer transducers can yield benefits such as lowered operation voltage, enhanced breakdown strength, and ease in impedance matching and that internal electrodes do not appreciably affect the piezoelectric and resonance characteristics of these devices. Multilayer construction offers extensive possibilities in terms of electrode design as exemplified by the piezoelectric transformer. This technique is uniquely suited to new, high-temperature ferroelectric materials, and tape casting is shown to have great promise for producing grain-oriented materials on a production scale.
