Abstract

The invention relates to an electrode array for a dielectrically impeded plasma treatment of a surface of a body, comprising at least one flexible flat electrode (1) and one dielectric (2) consisting of a flat flexible first material which protects the electrode (1) from the surface to be treated, with a layer (3) impeding a direct current flow. The dielectric (2) can lie on the surface to be treated, above a structure (4) with projections (7), air spaces (5) being formed between the projections (7) for the creation of the plasma, which have a side open towards the surface to be treated, and a bottom-side closure as a result of the layer (3) impeding the direct current flow. The structure (4) comprises a plurality of spacer elements (6) consisting of a second material that has less flexibility than the first material, and the projections (7) of the structure (4) are partially or completely formed by the spacer elements (6).
