The invention relates to a device for producing a cold atmospheric pressure plasma for the treatment of human and/or animal surfaces, comprising a flexible, planar multilayer system with a side facing the surface to be treated and a side facing away from the surface to be treated, wherein the multilayer system comprises the following layers, namely a first electrode layer on the facing away side of the multilayer system, second electrode layer on the facing side of the multilayer system, wherein the electrode layer has a plurality of recesses or is formed in a grid-like or meander-shaped fashion, a dielectric layer arranged between the first electrode layer and the second electrode layer, and a spacer layer arranged adjacent the second electrode layer on the facing side of the multilayer system. In addition, the invention relates to a cable, a generator unit for providing a high voltage, and a system.
