Identification of the mechanical state of DEAP transducers based on integrated DEAP sensors

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.
