Besides actuator and generator applications, dielectric electroactive polymers (DEAP) are also predestined for sensor applications to monitor the actual mechanical state based on the deformation dependent electrical pa- rameters of the DEAP. In order to ensure a high sensitivity, accuracy and dynamic a suitable sensor concept is required. Within this contribution a summary of multiple sensor concepts is presented, which are designed for positioning-actuators. To investigate these concepts, an FEM simulation is used, considering electrical and mechanical constraints. Furthermore, identification algorithms are presented to evaluate such sensor concepts.
