Piezoceramic for Large Piezocomposite and Fabrication Method thereof

摘要

The present invention relates to a large-area piezoelectric composite, which can overcome limitations of productivity by prevention of bending, and a manufacturing method thereof. The large-area piezoelectric composite of the present invention comprises: at least piezoelectric ceramic having a plurality of pillars vertically arranged in a support plate, wherein the piezoelectric ceramic includes a lattice part formed to be misaligned to face each other around the support plate; and first and second piezoelectric composite molded articles having the other piezoelectric ceramic corresponding to the piezoelectric ceramic to be arranged to maintain a predetermined space while being in contact with each other using the lattice part as a boundary, wherein the second piezoelectric composite molded article is coupled to an upper side of a space in which the first piezoelectric composite molded article is arranged.
