Platinum internal electrodes have been introduced into PZT compositions in a multilayer configuration by a conventional tape casting process. Electrical property data for the devices suggest that the piezoelectric coefficients of the multilayer configuration are approximately 20% lower than those of similar plain PZT devices. However, the applied voltage/displacement ratio is much lower in the multilayer compared to the plain devices. Resonant properties are almost unaffected by the presence of internal electrodes for hard PZT compositions. Piezoelectric transformers with multilayer primaries show improved transformer ratios compared to conventional devices.
