Monitoring the body water exchange using dielectric permeability method

摘要

Bioelectric impedance analysis (BIA) is a widely technique in determining body composition. In this method, two electrodes are placed at suitable points on the body and alternating current at different frequencies are passed through those points. Then, the voltage difference between the two points is measured and corresponding bioelectric impedance is calculated. In this study, BIA measurement calculated with dielectric permeability technique. This method differs from the conventional BIA in that, the measurement is totally noninvasive. In future studies, we will apply the proposed method in determining the amount of total body water and weight ratio of dry body mass for hemodialysis patients.
