Beschreibung
Zusammenfassung:	A phased array sensor assembly (100) is presented that can be permanently adhered to and impart ultrasonic waves to a structural surface and receive ultrasonic waves from a structural surface. The sensor assembly includes piezo-electric disks (120), a plurality of electrically conductive epoxy film adhesive contacts (140) positioned such that an electrical coupling is formed with the piezo-electric disks, piezo transducer flex wire trace circuits (150) aligned to be electrically coupled respectively with the electrically conductive epoxy film adhesive contacts on one end and including a plurality of wire trace electrical contact pads (155) on the other end, and a flexible polyimide layer (170). The polyimide layer includes laser ablated areas (175) for exposing the contact pads such that they can be electrically coupled with an external device.
