Paper Abstract

Piezoelectric polymer sheets are presently supplied with metallic electrodes that have thickness comparable to the polymer sheet, so the electrode stiffness considerably degrades the performance of actuators make of such sheets. Conducting polymers, such as PEDOT/PSS, may be a good substitute for metal as an electroding material given the high flexibility of polymers. The lower conductivity of polymers, though, forces consideration of the voltage distribution in the electrodes, which will not be uniform due to amplitude decay and phase lag. We have developed a simple analytical solution for the voltage distribution, and have found an excellent agreement with experimental measurements from piezoelectric bimorphs that have been constructed in our laboratory.
