Abstract: A method of fabricating and controlling a thick-film transducer array for steering and focusing ultrasonic waves within a substrate volume is provided. A ceramic film composition can be coated on a substrate volume in one or more layers. The ceramic film can be masked with a plastic sheet out of which an electrode pattern is cut. Conductive electrode material can be applied to the pattern to create a transducer array that can be polarized with an applied electric field. A method of controlling a thick-film transducer array comprises exciting one or more array elements to generate a wavefield in a substrate volume, the wavefield can be reflected by features within the substrate volume, one or more array elements can receive reflected wavefield signals, and images of the insonified substrate volume can be generated.

Abstract: The present invention is related generally to the field of non-destructive materials testing using ultrasonic devices, more particularly, ultrasonic devices in a phased array and includes a wedge for conducting pitch-catch ultrasonic phase array testing of materials wherein the wedge includes a liquid column and is manufactured with specific angles so as to control the angle at which the ultrasonic waves pass into the wedge and then are refracted when passing from the liquid in the liquid column into the material being analyzed, thus providing a wider range of analysis via sweeping the beams from the wedge than was possible with known wedges.
