Abstract
AbstractTo analyze the density of the current induced in the human body by the coupling phenomena of the ac electric field and the human body, the integral‐equation method and the finite‐element method have been proposed. However, there is no effective method for the analysis of the induced current density including the directional component in the model with a three‐dimensional human body shape by taking into account the conductivity of human tissues.The authors have developed a method for the analysis of the induced current density in the three‐dimensional shape model by a two‐step process consisting of: (1) the derivation of the induced current flowing in from the surface of the human model by the surface charge method; and (2) the application of these values as the boundary values of the finite‐element method using an isoparametric hexahedral element. The model can analyze the induced current density in the model by directly considering the conductivity and the permittivity of the human tissues. The results of the analysis of the induced current density in the present model have been confirmed from the experimental results of the metallic human model with the identical shape.
