Abstract
In this paper we discuss the electrical and mechanical modeling of dielectric elastomer stack actuators. The model is used to extract internal electrical parameters out of measurable values of the whole actuator system. Further parameters like the uniaxial Young's modulus, the assembly of the stack and the number of connected layers have to be considered. Using this data the static actuator performance for several driving conditions can be predicted. The final comparison of model based predicted deformation and real stack deformation show good accordance. Hence, the proven correlation of actuator layout parameters, fabrication parameters and driving conditions allow application dependent actuator design.
