Abstract:
A piezoelectric composite transducer array, comprising:a plurality of piezoelectric rods regularly spaced apart from one another, wherein a first surface region and a second surface region are defined at opposite ends of said plurality of piezoelectric rods and wherein a side region is defined about the periphery of said array between said first surface region and said second surface region;a viscoelastic material filling spaces between said first surface region and said second surface region;at least one electric conductor passing through said side region, extending into said viscoelastic material to a point at which said at least one conductor extends substantially parallel to said plurality of piezoelectric rods, and terminating at said first surface region; andat least one electrode positioned at said first surface region to be in contact with at least a portion of said plurality of piezoelectric rods and in electrical contact with said electric conductor.
