Abstract :
High voltage, short duration electrostatic discharge (ESD) measurements of human body impedance have been accomplished for different paths through the body. Skin contact impedance and intemal body impedance between various locations on the body were examined. Voltages from 1000 to 5000V were applied and the peak currents is 2.0 to 10A. The current waveform has time constant from 0.25 to 1.25 μs. The short time constant is consistent with safety requirements. The body impedance between the palm of the hand and the sole of the feet was found to be about 520 to 550Ω.
