Method of fabricating a piezoelectric composite apparatus

A method of fabricating a piezoelectric composite apparatus, comprising the steps of:

• providing a structure comprising a monolithic piezoelectric material having a first side and a second side;
• providing a backing sheet having an adhesive side;
• positioning the structure on the backing sheet such that the first side of the structure is attached to the adhesive side of the backing sheet;
• cutting through the structure positioned on the backing sheet to provide a plurality of piezoelectric fibers in juxtaposition, the plurality of piezoelectric fibers having first and second sides that correspond, respectively, to the first and second sides of the structure;
• providing a first film having a first conductive pattern and a second conductive pattern formed thereon, the first conductive pattern being electrically isolated from the second conductive pattern, the first and second conductive patterns each having a plurality of electrodes that cooperate to form a pattern of interdigitated electrodes;
• providing a second film;
• bonding the second film to the second side of the plurality of piezoelectric fibers;
• peeling the backing sheet away from the first side of the plurality of piezoelectric fibers;
• and
• bonding the first film to the first side of the plurality of piezoelectric fibers such that the conductive patterns of the first film electrically contact the plurality of piezoelectric fibers.
