surface modification

Portable plasma treatment system (1) for generating an anisothermal plasma for use on humans, comprising the components: a) a compressed gas cylinder (10) with a valve (11), the compressed gas cylinder (10) having a usable volume of no more than five liters, b) a hand-held device (20) with a plasma nozzle (21), the hand-held device (20) being designed and provided to generate the anisothermal plasma, c) a control unit (30) which is designed to regulate a gas flow flowing out of the compressed gas cylinder (20) and/or an electrode voltage in the hand-held device (20) so that the plasma can b

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).
