摘要： A device for generating plasma (1) comprises a high voltage electrode (10) as well as at least one external electrode (11, 12), wherein the high voltage electrode (10) at least in one coordinate direction (34) is arranged between conductive material of at least one external electrode (11, 12). The high voltage electrode (10) is covered with a dielectric (21) at least one side facing an external electrode (11, 12). Between the respective external electrode (11, 12) and the high voltage electrode (10) over its longitudinal extension at least one spacer element (20) is present, which at least in the region of its arrangement electrically insulates the respective external electrode (11,12) from the high voltage electrode (10) and which positions the respective external electrode (11, 12) at a constant distance from the high voltage electrode (10), wherein the spacer element is a gas-permeable foil.

摘要： The invention relates to a device for the treatment of free-form areas and zones of human or animal skin areas or plant surfaces by means of cold atmospheric-pressure plasma. The core of the device is a specific, preferably gas-permeable, electrode arrangement for generating a dielectrically impeded surface discharge where the earthed electrode is composed of electrically conductive textile material and the high-voltage electrode consists of a thin wire or electrically conductive thread which is sheathed with an insulting layer which has to meet specific requirements. On the basis of the present invention, it is possible to generate, in the area of diseased skin parts of the human body, in direct proximity to the skin surface or to wounds, a flat plasma for the treatment of the diseased areas which is acceptable in respect of the stress on the skin caused by temperature and electric potentials. The advantage of the gas-permeable textile sheet-like structure consists especially in that the arrangement can be placed flexibly onto variously curved surfaces and, in addition, offers the possibility of a gas exchange with the environment and/or the targeted dosing of a specific process gas mixture across the textile material into the active plasma zone.

摘要： The invention relates to a device (10) for treating a liquid with a plasma, wherein the device (10) has a high-voltage electrode (20) as well as a liquid-permeable ground electrode device (30). The ground electrode device (30) has a flat, conductive region (32) and a porous region (34) arranged on the flat, conductive region (32), wherein the conductive region (32) is liquid-permeable along its flat extension. A discharge space (40) is formed between the ground electrode device (30) and the high-voltage electrode (20). A first dielectric (50) is arranged on the high-voltage electrode (20) so that a plasma can be generated in the discharge space (40) by means of a dielectric barrier discharge. Moreover, the device (10) has an initial flow volume (60) into which the liquid (12) can be conducted, and that is surrounded by a wall (62). At least in a first region, the wall (62) of the initial flow volume (60) has the ground electrode device (30) such that the initial flow volume (60) is connected to the discharge space (40) in a liquid permeable manner via the ground electrode device (30).
