PPT-Shear Actuation of Piezoelectric Transducers for Ultrasonic

Hussain Altammar Mechanical Engineering Department University of WisconsinMilwaukee Objective The objective of this study is to investigate the feasibility of using shear mode piezoelectric PZT transducers in structural health monitoring for evaluation of adhesive joints. Piezoelectric materials generate an electrical charge in response to mechanical movement or vice versa produce mechanical movement in response to electrical input This report discusses the basic concepts of piezoelectric transducers used as sensors de Abstract Keywords Introduction Design 129 brPage 2br Ultra onic m tching ma terials Fig 1 ultrasonic trans ducer with backing and f ont tching m te ria Ultra onic b acking mate rials Materials A Piezocer amics 130 brPage 3br PIC 255 PIC155 Table1 Ergun Goksen G Yaralioglu and Butrus T KhuriYakub Abstract Capacitive micromachined ultrasonic transducers CMUTs introduced about a decade ago have been shown to be a good alternative to conventional piezoelectric transducers in various aspects s Ladabaum a XC Jin BT KhuriYakub A E L Ginztorl Lahorutory Stmfiwd Univrrsit Stutfiwd CA 94305 USA Abstract Significant improvement in the performance of capacitive microfabricated ultrasonic transducers is reported and the modifications which enable D.
