Method for manufacturing flexible laminated piezoelectric composite

A method for manufacturing a laminated piezoelectric composite, the method comprising:

• wet-mixing ceramic powder, a polymer binder, a plasticizer and a solvent for 4 to 72 hours so as to generate a mixed slurry, a content of the polymer binder in the mixed slurry being 3 to 10 parts by weight, a content of the plasticizer in the mixed slurry being 0.1 to 3 parts by weight, and a content of the solvent in the mixed slurry being 30 to 50 parts by weight, based on 100 parts by weight of the ceramic powder in the mixed slurry;
• introducing the mixed slurry into a tape casting process so as to prepare a plurality of piezoelectric composite sheets;
• drying and forming the plurality of piezoelectric composite sheets using a roll-to-roll process so as to prepare the plurality of formed piezoelectric composite sheets;
• forming internal electrodes on the plurality of formed piezoelectric composite sheets so as to prepare the plurality of piezoelectric composite sheets having the internal electrodes;
• laminating and pressing the plurality of piezoelectric composite sheets having the internal electrodes so as to generate a piezoelectric composite sheet laminate having the internal electrodes;
• and
• cutting the piezoelectric composite sheet laminate having the internal electrodes into a desired shape and size.
