A computational study of interactions of multiple plasma filaments in DBDs with human skin

Summary form only given. The use of atmospheric pressure air plasmas in direct contact with living tissue has therapeutic effects. When dielectric barrier discharges (DBDs) are used for this purpose, the plasma device typically contains the powered electrode while the tissue is the counter electrode.¹ The beneficial medicinal effects produced by these DBDs may involve large electric fields applied to or produced in the tissue, fluxes of chemically active neutral radicals and ions, and energetic species (VUV, ions) onto the tissue. These DBDs have filamentary and somewhat random structures, and so the treatment of the tissue is, at least locally, somewhat statistical.
