| Abstract(in English) | Contact currents flow from/into a human body, when contacting an object such as a metal structure with a different electric potential due to electromagnetic field exposure, which should stimulate muscle and peripheral nerves. In this context, numerical analysis of electric fields induced by contact currents in a human body have been performed so far, while the effectiveness of computational methods for transient contact currents has not been investigated sufficiently. Therefore, further numerical analysis of induced quantities in specific tissues is required. In addition, a previous study reported that a threshold contact current in the child which elicits biological responses is lower than that in the adult. Thus, further investigation for human models with different dimensions is required. Our group analyzed the induced quantities in a Japanese adult male model due to transient contact currents from charged human body with the FDTD method. We considered Japanese adult female model and 3-year-old child model in addition to the adult model, and then analyzed the in-situ electric fields due to transient contact current from charged human body. As a result, it was found that the decay constant for contact current of the 3-year-old child model whose capacitance is low was higher than that of the adult models for the same charged voltage. It was also confirmed that in-situ electric field becomes large around the metal rod and small sectional area on the current path. In-situ electric fields of 3-year-old child model were found to be higher than that of the adult models, because cross-sectional area of the hand and forearm of child model does not change so much as compared to that of the adults. |
