Abstract

In this work, we present on the characterization of the mechanical coupling in an array system of independent dielectric elastomer (DE) elements. The target device consists of a 1-by-3 array of silicone-based DE elements on a single silicone membrane. This DE-array is the basis for the development of a future DE-actuator array. To achieve large strokes in this DEA-array, the goal is to bias every DE element with a suitable nonlinear biasing element. A correct design of all biasing elements requires the knowledge of how the biasing of one DE-element influences the others and vice versa. After describing the potential influences of the coupling on the correct actuator design, a possible characterization method for the investigation of the coupling is presented. Furthermore, first results are shown and discussed briefly.
