Title:
EQUIPMENT USING PIEZOELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/107939
Kind Code:
A1
Abstract:
A complicated operation or process is performed by generating acoustic waves or oscillation by a piezoelectric device. Equipment includes the piezoelectric device provided with a piezoelectric element composed of a piezoelectric material, and a plurality of electrodes, which are arranged on the both planes of the piezoelectric element and are formed by a metal thin film pattern. On the piezoelectric element, a groove is arranged at a position on the external side of the electrodes.
