Abstract:
There are various measuring techniques to estimate the body compositions. Bioelectrical Impedance Analysis (BIA) is a technique that can be done easily and it is non-invasive. The number of electrodes of BIA attached to the body is generally four or eight. The eightelectrode system is popular, however it has small sensitivity at the trunk, hips, calves, and breasts. This may cause inaccurate assessments of body composition in particular, in women. In this engineering project, the main objective was to determine the performance of the ten-electrode system, which is the improvement version of the eight-electrode system by adding two electrodes at the belly. Fat was added in various regions of the body to evaluate the sensitivity performance. The results show that the body impedance obtained from the ten-electrode system was 1.26% higher than that of the eight-electrode system. The sensitivity was improved as well.
