【 摘 要 】

A Dielectric Barrier Discharge (DBD) device is developed to generate cold atmospheric plasma. Two different materials used as a top electrode: stainless steel and KCl liquid are considered. The bottom electrode is stainless steel for both cases. The gap of this DBD can be varied up to 3 mm. The DBD is powered by an AC high voltage in the range of ±10 kV with frequency in a range of 2-7 kHz. It is found that the discharge with KCl liquid electrode yield higher power than that with stainless steel electrode.
