A transducer is a device that converts energy from one form to another. Presently, piezoelectric material is commonly used as a basic component of transducers. Piezoelectric devices are a very reliable and inexpensive means of converting electrical energy into physical motion and exhibit a high tolerance to environmental factors such as electromagnetic fields and humidity. | ADVANCES IN PIEZOELECTRIC TRANSDUCERS Edited by Farzad Ebrahimi Advances in Piezoelectric Transducers Edited by Farzad Ebrahimi Published by InTech Janeza Trdine 9 51000 Rijeka Croatia Copyright 2011 InTech All chapters are Open Access distributed under the Creative Commons Attribution license which allows users to download copy and build upon published articles even for commercial purposes as long as the author and publisher are properly credited which ensures maximum dissemination and a wider impact of our publications.
