摘要

High performance clinical and industrial ultrasonic transducersnrequire an impedance matching layer with controlled acoustic propertiesnfor efficient coupling of acoustic energy between the piezoelectricnlayer and the propagating medium. The principles of operation, designnrequirements and performance of a novel integrated impedance matchingnlayer are discussed here. This integrated impedance matching layer is ancomposite of inert lead zirconate titanate (PZT) ceramic and conformalnpolymer filler material
