Advances of atmospheric-pressure dielectric-barrier-discharge plasma jets

Atmospheric-pressure dielectric-barrier-discharge（APDBD） plasma jets represent one of rapidly developing technologies of non-thermal atmospheric pressure plasmas, which have attracted much attention of researchers in recent years. Their unique features, such as lower capital costs and operation convenience, have made them become a powerful tool for promoting a number of rising interdisciplinary applications. In this paper, the advances of the commonly used APDBD plasma jet sources are reviewed with the burgeoning novel interdisciplinary research field of plasma bio-medical science as the research background. Based on the analysis concerning the design ideas and characteristics of different APDBD plasma generators, the challenges for improving the performances of the APDBD plasma jets employed in actual applications are discussed; and subsequently, the brief discussions on the designs, as well as the features, of the large volume, uniform and stable helium and argon APDBD plasma jets are presented.
