Abstract: The production of stacked dielectric elastomer actuators or sensors is intended to be improved in such a way that, with reduced technical expenditure, a reproducible homogeneous distribution of elastomer material with a defined layer thickness is possible in a short time without a further subsequent homogenizing treatment step on a resultant dielectric layer. This is achieved by using expanding means for expanding a material jet of an elastomer emerging from a coating nozzle (21), which, after being made to expand in a y direction, can be deposited on a substrate over which the coating nozzle (21) can be moved in an x direction by means of a screen device (2). A suspension for producing electrode layers is also disclosed, as is a way of producing flexible contact lines by injecting conductive material into connecting channels within the stacked dielectric elastomer actuator.
