Patent ID: 7424771

Claim:
A method for producing a piezocomposite, comprising the steps of: (a) preparing a sintered piezoelectric plate having a thickness ranging from 10 μm to 500 μm; (b) forming a resin layer on the sintered piezoelectric plate; (c) forming a plurality of parallel cut grooves in the sintered piezoelectric plate provided with the resin layer, without completely dividing the resin layer, so as to cut the sintered piezoelectric plate into a plurality of sintered piezoelectric thin wires; (d) repeating the steps (a) to (c) a plurality of times, so as to prepare a plurality of composite sheet units on a surface of each of which a plurality of the sintered piezoelectric thin wires are arranged in a uniform direction; (e) laminating a plurality of the composite sheet units so that the sintered piezoelectric thin wires are positioned between the resin layers; and (f) integrating the plurality of the composite sheet units after the laminating to obtain said piezocomposite.
