Abstract :
In Human Body Communication, it is important to investigate the input impedance characteristics of the electrodes for improving the qualities of communication. For rapid analysis and development of phantom, an approximation model is needed. In this paper, we proposed newly developed homogenous human arm model which consists of single material. Input impedance characteristics of the homogenous model were compared with that of conventional model which has a multilayered cylindrical structure. As a result, it was found that the input impedance characteristics obtained from two models were well consistent at 10 MHz. On the other hand, it was found that transmission characteristics and electric fields around the model were different in each model.
