Abstract
A method is described for making a piezoelectric composite for building an acoustic transducer from two or more pieces of piezoelectric material. Each piece of material is cut to form slots or trenches having a uniform pitch spacing and material portions of uniform width such that the material portions of one piece may be received within the slots or trenches of the other. The pieces are then interdigitated and joined to make the piezoelectric composite.
