The shape of the plasma jet by the dielectric potential barrier discharge method varies depending on the applied flow rate and the size of the electric field, and this change is represented by the difference in the spectral distribution due to the difference in density of the DBD plasma jet. The difference between the generation and intensity of active species through the analysis of the spectrum of the generated plasma jet is an important factor in utilizing the device. In this paper, a prototype of an atmospheric pressure volume DBD type plasma jet generator injected with Ar gas was designed and manufactured according to the proposed design method. In order to generate the optimized shape of the plasma jet, the optimum plasma jet shape was generated while sequentially increasing the applied power, and in order to analyze the characteristics of the generated plasma jet, the characteristics of the plasma jet using a spectrometer were analyzed. The optimization design technology of the plasma jet generator according to bio-application was verified by confirming the method of establishing an optimal plasma jet shape in the plasma jet generator through the design method of the proposed system and the results of active species on EOS.
