Abstract

The present invention provides a plasma source in the form of a pad so that a user discretionally wears the plasma pad, i.e., present invention provides a wearable plasma pad that is conveniently worn by a user for the purpose of a long period of contact to plasma, fabricated discretionally into various shapes and areas and appropriately responds to the body part that requires a plasma therapy. The plasma pad according to the present invention is fabricated with a flexible base plate on which a high voltage electrode coated or layer with dielectric materials and a ground electrode are arrayed. AC voltage is applied to the high voltage electrode so that the plasma pad generates plasma between the electrodes by means of atmospheric discharge. Products such as patch, bandage, cap, hair-band, socks, etc. may be achieved based on the plasma pad thus fabricated.
