Abstract
A double-sided flexible circuit is used to provide interconnection to a piezoelectric ultrasonic transducer array. The ultrasonic crystal is covered with first and second electrode layers having an insulation gap provided therebetween. The flexible circuit material is then bonded to the first and second electrode layers so that one side of the double sided flexible circuit makes contact to one set of transducer electrodes and the other side of the flexible circuit makes contact to the second set of transducer electrodes. The ultrasonic transducer desirably includes a concave acoustic lens having an acoustic velocity greater than water.
