Paper Abstract
Interdigitated electrodes(IDEs) piezoelectric fiber composites is one kind of new smart materials which can be used as
actuators in many applications because of its unique properties such as high induced stain and easy integration on curved
surface of the base structure. In this paper, basic theories about composite were introduced briefly firstly. Then
Electrostatic Field of this special electrode was analyzed. Finally, Finite Element Method is employed to numerically
research the influence of thickness and material constants of polymer around electrodes, volume ratio of fibers and
dimension of electrodes on the composite's induced strain and stress. The results show that the actuating strain and stress
of interdigitated electrodes piezoelectric fiber composites can be improved much by employing polymer having high
dielectric constant or decreasing the thickness of the polymer around IDEs. In addition, much higher induced strain and
stress can be got by decreasing period of IDEs or increasing width of IDEs and volume ratio of fibers among the
composite. At last, the maximum strain (280με) was got from the numeric model of optimized samples, which is very
large considering composite is not pure PZT ceramics.
