Abstract : The patent concerns a transducer region of an ultrasonic delay line which includes first and second off-set electrode layers located on opposite sides of a piezoelectric layer with only portions of the electrodes being aligned. The first electrode is disposed over part of a surface of the delay line, the piezoelectric layer is located over part of the first electrode and the second electrode is partially located over the piezoelectric layer in alignment with said part of the first electrode. The offset electrodes permit simple solder connections to be made to a lumped parameter matching impedance without damaging the piezoelectric material.
