| Abstract(in English) | Contact current occurs when the human body comes into contact with an object at a different electric potential, and biological effect is caused by internal electric field. Therefore, the reference level is regulated in terms of injected contact current in the international guidelines/standard. In previous studies, relationship between reference level and basic restriction that is a permissible electric field value induced in the body is discussed. It has been reported that their relationship is inconsistent when one touches with fingertip. Therefore, it is necessary to conduct the dosimetry for contact current with fingertip. The present study discussed numerical investigation of hand impedance by finite-difference time-domain (FDTD) method to verify the computational modeling of contact current. First, we investigated an applicability of the quasi-static FDTD method for a human body in MHz region. Then, we compared measured and simulated results of a hand impedance to confirm the validity of computation. |
