24 August 2000 Electromechanical characterization of screen-printed PZT thick films
Author Affiliations +
Thick soft and hard-PZT films have been fabricated on different geometries of Alumina substrates using a screen-printing technique. Three mechanical characterization tests were set up to determine Young's modulus of the films: dynamic, quasi-static and nanoindentation tests. A Young's modulus around 52+/- 7 Gpa was calculated. The piezoelectric coefficient d31 was also investigated and is found to be close to -33pC/N. The fabricated films showed also good performances when used in damping control.
