摘要

The present invention is a ceramic which is formed by a regular arrangement of the multilayer piezoelectric block, and the multilayer piezoelectric block in the polymer matrix provides a polymer 1-3 piezoelectric composite. A piezoelectric multi-layer block of the present invention is in particular produced by a low temperature co-sintering, and co-extrusion method, a plurality of the internal electrode layer (s) one less than the number of the piezoelectric layers and the piezoelectric layer interposed therebetween comprising a piezoelectric material consisting of the multi-layer block, and which is in contact with the internal electrode layers from the side of the multi-layer block to form a voltage to each of the piezoelectric layer by a lamination or a coating itself on a lower upper surface, or of the multi-block or through the internal electrode layer It has the unique arrangement and structure that includes a pair of outer electrode layers. With this arrangement and structure piezoelectric multi-layer block of the present invention, as well as the lateral vibration mode in which they occur in the longitudinal direction of the piezoelectric layer is to generate a high displacement at a low voltage by amplifying the longitudinal vibration mode of the virtual high at low frequencies to It has made an effort. Therefore, the multilayer piezoelectric block and a ceramic of the present invention-polymer 1-3 piezoelectric composite can be suitably used in the ultrasonic oscillator. ; Multilayer piezoelectric block, the piezo-electric composite, the piezoelectric body, the lateral vibration mode, the ultrasonic oscillator, the internal electrode, a ceramic polymer composite
