An Investigation of Elastic and Dielectric Loss Processes in Piezoelectric Polymers and Their Effect on Broadband Sonar Transducers*
Tuesday, February 23, 1993 3:30 p.m. Deborah A. Summa Applied Research Laboratories The discovery of strong piezoelectric activity in macromolecules such as poly(vinylidene fluoride) (PVDF) and its copolymers has made possible a class of flexible, lightweight, inherently broadband transducers which exhibit virtually no lateral coupling. Recent technological advances have made possible the mass production of…
