A system including a wearable cold plasma system, including a wearable cold plasma applicator configured to couple to and deliver a cold plasma to a surface of a user wearing the wearable cold plasma device.

In a plasma treatment arrangement for carrying out dielectrically impeded plasma discharge onto a surface to be treated having a flat electrode unit (4) which has a treatment side, and a control unit (11) which supplies at least one electrode (19) of the electrode unit (4) with a high-voltage AC potential for a power which is required for plasma generation between the at least one electrode (19) and a counterelectrode which forms a reference potential, wherein the at least one electrode (19) which receives the high-voltage AC potential is shielded with a flat dielectric (7), at least on the treatment side, and wherein the flat electrode unit is designed to reduce the size of its support area on the surface to be treated for the purpose of adaptation to the size of the surface to be treated, the adaptation of the support area of the flat electrode unit (4) becomes possible in an unproblematical manner on account of the control unit (11) having a device (14) for determining the size of the adapted support area and a control device for adjusting the power to be output to the at least one electrode (19) in accordance with the determined size of the support area.

A plasma device for treating surfaces, in particular surfaces of fabrics. In order to allow for better ease of handling, an elongate housing is provided which can be manipulated with one hand and in which a plasma source is arranged. The plasma source has a plateau surface that extends in the longitudinal direction of the housing and includes at least one electrode via which plasma can be dispensed onto the surface to be treated. A center of gravity M and a geometrical center G are located at a distance of less than 20 mm from one another.

Provided is a plasma device for applying a cold atmospheric plasma to a surface to be treated, in particular on textiles, leather and/or plastic fibers. The plasma device includes a housing, a plasma source in the housing, and a voltage source in the housing for applying a voltage to the plasma source, wherein the plasma device is configured to enable activation of the plasma source and/or to selectively switch the plasma source on only if a distance between the plasma source and the surface to be treated is within a predetermined distance.
