Bioelectrical impedance analysis BIA is used to analyze human body composition by applying a small alternating current through the body and measuring the impedance.

BIA non-invasive body analysis -

Our study explored a novel method that uses considerably small electrodes that can be adapted into small devices, such as a wristwatch. Figure 7 shows the calculated contact resistance distribution of the study participants. While the average value was Ω, it is notable that the maximum value was as high as Ω.

Figure 8 a shows the impedance correlation between our device and the whole-body composition analyzer. The coefficient of determination R 2 of impedance was 0. This result shows that there is a strong correlation for impedance measurements between the wrist-wearable bioelectrical impedance analyzer and the whole-body bioelectrical impedance analyzer, and the proposed contact resistance compensation method improves the correlation coefficient effectively.

Figure 8 b shows the correlation of percentage body fat measurement between our wrist-wearable bioelectrical impedance analyzer and the reference instrument DEXA , from which it can be seen that R is 0.

The SEE was estimated to be 3. It can be seen that the errors between the two instruments are randomly distributed without any skewed tendency and Table 3 shows the comparison of accuracy in measurement of percentage body fat by the whole-body composition analyzer, the upper-body portable body fat analyzer, and our wrist-wearable bioelectrical impedance analyzer.

We developed a novel wrist-wearable bioelectrical impedance analyzer with a contact resistance compensation function such that bioelectrical impedance can be accurately estimated even with considerably small sizes of electrodes outer electrodes: 68 mm 2 ; inner electrodes: mm 2.

The correlation coefficient and the SEE of percentage body fat relative to the DEXA instrument were estimated to be 0. Considering that the measurement time of our wrist-wearable BIA device was only 7 s and could be reduced further, this sensor technology provides a new possibility for a wearable bioelectrical impedance analyzer with more miniature electrodes toward daily obesity management.

Perry Wilson Journal of Cardiovascular Translational Research The Investigation of Bio-impedance Analysis at a Wrist Phantom with Two Pulsatile Arteries Yang Yu Andrew Lowe Huiyang Zhang Cardiovascular Engineering and Technology BIA has been applied to assess the mass distribution and water compartments in the BC.

BIA has several parameters: fat mass, fat-free mass, total body water, phase angle, and body mass index; these parameters show the body distributions. However, more studies need to improve validity and reliability, according to these aspects.

The purpose of this review was to briefly theoretical procedures of numerous compartments models of body composition. Published in: International Congress of Advanced Technology and Engineering ICOTEN. Article :.

Percentage of body BIA non-invasive body analysis is strongly associated with the risk of several chronic diseases but its accurate measurement is difficult. Bioelectrical impedance analysis BIA is a relatively simple, quick and non-invasive technique, to measure body composition. It measures body fat accurately in controlled clinical conditions but its performance in the field is inconsistent.
