| Research Abstract |
Contact current and human body resistance calculated by using precise human model at power frequency showed good agreement with another numerical data. However, those are twice or three times higher than the experimental ones, ranging 550 to 800 ohms, measured for 26 volunteers with various ages (21-66 years old) and BMIs (16.1-41.4 kg/m2). It is found that R decreases as BMI increases, and that the measured profiles of relative R along the current path are in good agreement with the numerical ones. The contact current around the heart concentrates to the lung and heart that have relatively high conductivity, and its direction strongly depends on the contact scenarios.
