  • Piezoelectric composites and methods for manufacturing same
    Patent number: 6984284
    Abstract: A method is described for making a composite, such as a piezoelectric composite, having a predetermined volume ratio. Initially, a pair of base slabs are diced to form slot having uniform pitch spacing such that a material portion of one diced base slab may be received within the slots of another diced base slab. The diced base slabs are interdigitated and joined to form a first piezoelectric composite that can subsequently be diced to form slots having a uniform pitch spacing that are spaced from the first slots. Two diced first piezoelectric composites are interdigitated and joined to form a second piezoelectric composite of reduced volume ratio and finer pitch.
