Abstract (in Japanese) (See Japanese page) 
(in English) A transcutaneous energy transmission system (TET) is used for transmitting energy to artificial hearts using electromagnetic induction. It can reduce the risk of infections caused by percutaneous connections and improves quality of life (QOL). In this study, we analyze the electromagnetic effects of TETs on a human body implanted with a totally artificial heart. The SAR and current density in two human body models (1 and 2) consisting of forty-three different organs are analyzed using an electromagnetic simulator (Microstripes, AET Inc.). Model 1 is embedded with air-core coils and it is based on the pectoralis major muscle located near the collarbone. Model 2 is an expanded form of model 1 with an external battery, an internal controller, an internal battery, an actuator, and pumps additionally embedded in it. The maximum SARs in models 1 and 2 are 58.1 and 31.5 mW/kg, respectively, and the corresponding maximum current densities are 3.72 and 2.63 A/m$^{2}$, respectively. The SAR and current density values are below the limiting values prescribed in the ICNIRP guidelines.
