The design and experiment of the leg model based on galvanic coupling intra-body communication

Abstract

The phantom model of the leg based on galvanic coupling IBC (intrabody communication) was established to simulate the channel characteristics of human body. The 3D reconstruction of human’s leg was carried out by using the data of real man. It’s outer contour was printed by the 3D printer, then filled it with the special solution to obtain the phantom model. To verify whether the phantom model can be conformity with reality, the in vivo experiment was done. The experimental results showed that the outcome of the phantom experiment was consistent with that of the in vivo experiment, while the channel length range from 4 cm to 30 cm and the frequency was at 10 kHz–500 kHz. The absolute value of the error of corresponding data was less than 7 dB. It turned out that the phantom model restructured by the real human image data could simulate the real galvanic coupling IBC channel better.
