Abstract

A portable Ar plasma jet (size: 347 × 300 × 145 mm, weight: 6 kg including the gas bottle) powered by a battery for direct human treatment is developed, and the discharge characteristics are investigated with the human equivalent circuit model in this study. The root-mean-square value and the specific single pulse energy of the discharge current are calculated as a combination to estimate human contact safety from the perspectives of average effects and instantaneous effects. The equivalent circuit model built at the end figures out the essential parameter, plasma plume resistance, which mainly affects the electrical safety for human contact. The portable plasma device could extend its biomedical applications, and the electrical safety assessment methods would be a reference for other plasma devices.
