  • METHOD AND DEVICE FOR PRODUCING AN ELASTOMER STACK ACTUATOR
    Publication number: 20160204338
    Abstract: A method for producing an elastomer-based film stack actuator may include: a starting process of: providing an elastomer film having an elastomer layer and two cover layers, and removing one of the two cover layers to produce a delaminated film; a stacking process, of: applying a layer of electrodes to the elastomer layer of the delaminated film assembly, laminating an additional delaminated elastomer film on the film assembly having electrodes, and removing one of the two cover layers from the laminated film assembly to produce a delaminated film assembly; and a finalization process of: contacting the electrodes of the film assembly produced by the stacking process, separating the stacking actuators of the film assembly produced by the stacking process, and encapsulating the separated stacking actuators. The stacking process steps may be repeated by using the delaminated film assembly of the final step in the initial step.
