摘要: A method for assembling an ultrasonic transducer, first produces a plurality of plates piezoelectric material. Then the are bonded together through use polymeric matrix comprising polymer and intermixed particles having determined dimensional parameters, acting to separate by predetermined distances that dependent upon parameters. Preferred polystyrene spheres. second embodiment strips green ceramic material, each strip including layer fugitive The then placed in stack is fired convert material into densified plates. firing acts drive off said leave voids. voids backfilled with create unified structure.
