Abstract

A phased array ultrasonic transducer includes a bonding wire structure, a damping material, a plurality of ultrasonic transducers, and a printed circuit board. The bonding wire structure includes a plurality of bonding wire elements. The damping material surrounds the bonding wire structure and is interposed with the plurality of bonding wire elements. The plurality of ultrasonic transducers is arranged in a matrix beneath a membrane, each of the plurality of ultrasonic transducers being coupled to a corresponding bonding wire element of the plurality of bonding wire elements. The printed circuit board includes a plurality of circuits. Each of the plurality of circuits is coupled to a corresponding bonding wire element of the plurality of bonding wire elements.
