The transmission characteristics of intra-body communication (IBC) are studied. Methods: Taking the most commonly used part in human body communication, the human arm, as the starting point, the equivalent mathematical model of the arm is reasonably abstracted and obtained, and then the finite element method is used to explore the current distribution mechanism in the human body. In addition, by applying different forms of electrical signals to the model, the channel characteristics of the human body are compared and analyzed. Results: 1. Within the safety threshold, the magnitude of the injected human body current has little effect on signal attenuation; 2. The signal attenuation decreases with the increase of the size of the transmitting electrode; 3. The greater the distance between the transmitting and receiving electrodes, the greater the signal attenuation; 4. The human body communication current mainly flows through the muscle layer, but with the increase of frequency, the skin effect is obvious, and the proportion in the bone is very small, which is enough to be ignored. Conclusion: The equivalent finite element model of the human arm proposed in this paper can be used to analyze the communication mechanism of current-coupled human body communication.
