ABSTRACT:
A transducer is provided having interconnections between a conductive member and one side of a heat sensitive piezoelectric substrate such as PVF.sub.2 to or from which electric signals flow. The interconnections are positioned on one side of the substrate with the opposite side having a metalization under the interconnection attachment positions and in a continuous region therebetween. The interconnection includes adhesive material such as epoxy disposed between and attaching an electrically conductive member to one side of the substrate and a single contiguous electrically conductive coating applied to adjacent portions of these two members to electrically connect them. Since both interconnections are positioned on one side of the substrate the transducer is adhesively fastenable to operational structure with a strong bond line, permits lead attachment after mounting and prevents lead shortout. Various electrode shapes, sizes and patterns may be constructed to allow power channeling and to produce focusing of the transducer signal.
