Paper Abstract

The focus of this paper is on the modeling of dielectric elastomer actuators and generators. One of the effects that is rarely considered in modeling of these systems is the influence of the materials' specific resistance on the performance. The non-ideal electrical properties of both elastomer and electrode material will cause undesired parasitic effects. Although for most laboratory scale prototypes these effects are hardly recognizable, they may however play an important role for larger structures and especially for dynamic applications. Therefore, an analytical model is developed and presented in this paper which can give helpful instructions for the design and fabrication process of EAP-systems. It is proven to be valid by means of the finite element method and subsequently extended for more complex systems.
