Fabrication, properties and design considerations of piezocompositetransducers for ultrasonic imaging

摘要

The piezocomposites possess better acoustic matching with humantissue. These are broad-band devices which provide axial resolution andcan be made to operate at high frequencies. The present paper reportsthe fabrication technique adopted by the authors along with importantresults for 0-3 and 1-3 type piezocomposite transducer elements
