Abstract: In an array of a plurality of plasma generator modules for generating a physical plasma by dielectric barrier discharges at atmospheric pressure, each of the plasma generator modules comprises two parallel electrodes linearly extending at a lateral distance, one of which having a dielectric barrier; connection devices for connecting the electrodes to a high voltage source; two flat gas-conducting elements conducting a working gas between the electrodes; and a module housing delimiting the respective plasma generator module laterally along the electrodes and transversely to the electrodes. The module housings are fixed to one another or to a common module frame by means of fixation devices. The module housings are arranged side by side both in a first direction along and in a second direction transverse to the electrodes, and in such an offset way that the electrodes of the plasma generator modules partially overlap in the direction along the electrodes.

Abstract: To dry a hand with fingertips and a carpus, the palmar aspect and the dorsal aspect of the hand are blown dry, starting from the fingertips, by a pair of planar gas jets, wherein the gas jets of the pair run towards each other in the direction from the carpus to the fingertips at an angle of less than 180°. By applying high-voltage AC pulses with respect to ground to dielectrically shielded electrodes arranged next to both planar gas jets, direct discharges are obtained across the hand on the palmar aspect thereof and on the dorsal aspect thereof.
