Fangming Ruan, Yoshinori Taka, Osamu Fujiwara, You-Gang Gao, Dan Shi · 2008
A couple of discharge parameters are measured and analyzed, correlation investigation are performed between charge voltage, approach speed and discharge parameters. Rampe-Weazel formula is employed to model short-gap electrostatic discharge(ESD) in air from charged human body. Threshold phenomenon appears at charge voltage of 800V; discharge parameters reach extreme values whereas the strongest effect exists for approach speed on discharge parameters. The influence of charge voltage and approach speed on discharge parameters has an obvious reductive tendency for charge voltage below 600V or over 1000V.
