Abstract

The work presents a simulation analysis of the bioimpedance at the human upper arm using the finite element method (FEM). Comsol Multiphysics has been used to create the 3D model with four domains of dielectric behavior: skin, fat, muscle, and bone. The main objective of this paper is to study the effect of the fat thickness and frequency on three parameters: resistance, reactance, and phase. The impedance values were calculated as the ratio of the output voltage at the electrodes and the applied current (1 mA). The measurements were done at four different values of the fat layer (10mm, 15mm, 20mm, and 25mm) and the electrical properties of the upper arm were used. The results clarify that the fat layer has a significant impact on the upper arm impedance across the frequency spectrum, resistance, and phase appear to be more affected than reactance.
