“…In [5], M. Wegmueller et al compared simulations with measurements to study the influences from the electrode size, human joints between transmitter (TX) and receiver (RX), and electrode positions on signal attenuation in the human body. The mathematical modeling, simulation and system implementation of intra-body communication were reviewed in [6]. M. Callejón et al [7] simulated the electric field and current density through differ-ent tissues as a function of frequency, in addition to studying the influence of different channel lengths on the signal pathloss at an operating frequency of 40 kHz.…”

“…By definition, both of these techniques differentiated by the connection from transmitter to receiver component as shown in Figure 2 [6]. In galvanic coupling, two set of transmitter and receiver electrodes that attached to human skin will operate to process the applied signal [7] while capacitive coupling technique provides the signal processing by current loop between the transmitters and receiver electrode that form a return path through the external ground [8].…”

Galvanic coupling method is one of the methods introduced in intra-body communication (IBC). IBC uses human body to as the communication medium for data transmission. In this paper, the investigation focuses on signal attenuation performance across knee joint using the galvanic coupling analysis. The signal attenuation was determined by implementing the galvanic coupling analysis at specific knee flexion angle. The galvanic analysis initiated by deciding the operating frequency in between 40 to 60 MHz in order to analyze the signal attenuation between the knee flexion angles. This paper found that the lowest signal attenuation at the operating frequency was 47.25dB, while the highest one was 52.63dB where the knee flexion angle is 0o and 155o respectively. It was concluded that the signal attenuation decrease with the increasing of knee joint existence at the specific flexion angle. However, a wider experiment must be conducted for various data that will correspond to signal attenuation for various influenced human data characteristics.

“…Kibret et al [ 12 ] calculated the electrode-skin impedance in a a new way and generated an equivalent upper arm as a circuit model. A complete transfer function was obtained on the basis of an improved four terminal circuit model by Song et al [ 13 ]. Pun et al [ 14 ] came up with an analytical quasi-static electromagnetic model for the IBC signal distribution in the human upper arm.…”

Existing research on human channel modeling of galvanic coupling intra-body communication (IBC) is primarily focused on the human body itself. Although galvanic coupling IBC is less disturbed by external influences during signal transmission, there are inevitable factors in real measurement scenarios such as the parasitic impedance of electrodes, impedance matching of the transceiver, etc. which might lead to deviations between the human model and the in vivo measurements. This paper proposes a field-circuit finite element method (FEM) model of galvanic coupling IBC in a real measurement environment to estimate the human channel gain. First an anisotropic concentric cylinder model of the electric field intra-body communication for human limbs was developed based on the galvanic method. Then the electric field model was combined with several impedance elements, which were equivalent in terms of parasitic impedance of the electrodes, input and output impedance of the transceiver, establishing a field-circuit FEM model. The results indicated that a circuit module equivalent to external factors can be added to the field-circuit model, which makes this model more complete, and the estimations based on the proposed field-circuit are in better agreement with the corresponding measurement results.
