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 WALL FOLLOWER. © 2015, EV3Lessons.com, Last edit 11/17/2015.
