DEVICE AND METHOD FOR GENERATING COLD PLASMA.

摘要

A device (1 ) for generating cold plasma for treating a three-dimensional surface using a "dielectric barrier discharge" technique, comprises an electrode (4) connectable to a high-voltage generator (5) and a layer (3) of deformable dielectric material, having a first face coupled to the electrode (4) and a second face juxtaposable with the surface to be treated, the latter defining a counter-electrode; the electrode (4) is made from a liquid or semi liquid material with low electrical resistivity and the dielectric layer (3) is made from a material which is impermeable to that liquid.
