Electrode array for a dielectrically impeded plasma treatment

An electrode arrangement for a dielectric barrier plasma treatment of a surface of a body, comprising:

• at least one flexible planar electrode;
• a dielectric material made of a planar flexible first material which includes a layer that shields the at least one flexible planar electrode from the surface of the body to be treated and prevents a direct current flow,
• wherein the dielectric material is configured to rest on the surface of the body to be treated via a structure having projections,
• wherein air spaces for formation of a plasma are between the projections,
• wherein the structure comprises
• a side open toward the surface of the body to be treated,
• a bottom-side termination by the layer of the dielectric material which prevents the direct current flow, and
• a plurality of spacer elements made of a second material, wherein a flexibility of the second material is less than the flexibility of the first material, wherein the projections of the structure are partially or completely formed by the spacer elements.
