“…In this way, parameters R ext,t and R int,t determine the values to which the bioimpedance tends respectively at low and high frequencies. On the other hand, parameter C m,t is related to the time constant of Z a and therefore controls its dynamics over frequency [31]. Subsequently, their values were chosen in order to emulate approximately a frequency response similar to that found in the literature.…”

“…However, only few bioimpedance data exist in the IBC literature. For this reason, and with the end of obtaining a general expression, the real and imaginary parts of the impedance were plotted in a Cole diagram and a least-mean-square algorithm was applied to obtain a curve-fitting, from which the parameters of a three-dispersion Cole-Cole model were derived [28]:…”

Galvanic coupling in intrabody communication (IBC) is a technique that couples low-power and low-frequency voltages and currents into the human body, which acts as a transmission medium, and thus constitutes a promising approach in the design of personal health devices. Despite important advances being made during recent years, the investigation of relevant galvanic IBC parameters, including the influence of human tissues and different electrode configurations, still requires further research efforts. The objective of this work is to disclose knowledge into IBC galvanic coupling transmission mechanisms by using a realistic 3-D finite element model of the human arm. Unlike other computational models for IBC, we have modeled the differential configuration of the galvanic coupling as a four-port network in order to analyze the electric field distribution and current density through different tissues. This has allowed us to provide an insight into signal transmission paths through the human body, showing them to be considerably dependent on variables such as frequency and inter-electrode distance. In addition, other important variables, for example bioimpedance and pathloss, have also been analyzed. Finally, experimental measurements were also carried out for the sake of validation, demonstrating the reliability of the model to emulate in general forms some of the behaviors observed in practice.

“…Furthermore, it may be useful to examine the effect of different diseases of the autonomic nervous system like the Parkinson's disease [13,14], for monitoring pregnant women [15,16], for diagnosis and treatment of patients with hypertension [17,18]. Likewise, it has been used to monitor surgical operations [19,20] and dialyzed patients [21,22].…”

Impedance cardiography (ICG) is a non-invasive tool for assessing the hemodynamic parameters. It has been used for diagnosing several cardiovascular diseases, such as heart failure, cardiomyopathy, and valvular diseases. Particularly, the valvular heart disease is characterized by the damage in one of the four heart valves: the mitral, aortic, tricuspid or pulmonary valves. The mitral valve insufficiency and the aortic valve stenos are the most frequent valve diseases in the world. In this paper, we propose to diagnosis the mitral valve insufficiency using the impedance cardiography technique. The study group consisted of 40 subjects (20 control subjects and 20 patients with mitral insufficiency). A parameter "I" is calculated from the impedance cardiogram waveform and it is used to differentiate control subjects from patients with mitral insufficiency. The parameter "I" was related significantly to the abnormalities of the impedance cardiogram waveform. For patients with mitral insufficiency, "I" was higher than for the healthy subjects with a difference ratio of 89% (p<0.001). To improve the diagnosis, we determined the stroke volume, cardiac output, and other hemodynamic parameters for the two groups of subjects. Finally, we concluded that we could identify, easily, patients with mitral insufficiency based on the abnormalities of the impedance cardiogram tracings and a characteristic parameter "I".
