Research Abstract

Distributions of 60Hz contact current inside the anatomically realistic human body were demonstrated under typical scenarios of current paths. Current densities and electric fields in the CNS tissues or the heart, the heart-current ratios, and heart-current factors were calculated. The new numerical method which was partly modified from the conventional SPFD method was proposed. Average values of the electric fields in the heart of the model due to the contact current of 0.5mA were 65~85mV/m for the hand-to-foot/feet current paths. It is found that a part of 33~40 % of the total contact current passes through the heart in three scenarios of one hand to either the other hand or feet, and these heart-current ratios were much larger than the ones reported by another researcher. Furthermore, the heart-current factor is almost the same as the one in IEC for the right-hand-to-feet, but is twice as much as the one in IEC for the hand-to-hand path.
