Abstract :
In human body communication system, it is important to investigate the input impedance characteristics of the electrodes for improving the qualities of communication. For rapid and freedom analysis, an approximation model is needed. In this paper, we compared input impedance characteristics of detailed model with that of approximation model which has a multilayered cylindrical structure. As a result, it was found that the input impedance characteristics of two models were well consistent in the frequency range of 1 MHz to 1 GHz. Moreover, it was found that electric fields around the arm were almost the same in each model. These analysis results show that the multilayered cylindrical model is useful for calculating input impedance and electric field distributions around the arm model.
