Abstract:
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 tat the first side of the structure is attached to the adhesive side of the backing sheet; slicing 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; removing the backing sheet 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.
