Skin-Electrode Contact Area in Electrical Bioimpedance Spectroscopy. Influence in Total Body Composition Assessment.
2011 (English)Conference paper (Refereed)
Electrical Bioimpedance Spectroscopy (EBIS) has been widely use for assessment of total body composition and fluid distribution. (EBIS) measurements are commonly performed
with electrolytic electrodes placed on the wrist and the ankle with a rather small skin–electrode contact area. The use of textile garments for EBI requires the integration of textrodes with a larger contact area surrounding the limbs in order to compensate the absence of electrolytic medium commonly
present in traditional Ag/AgCl gel electrodes. Recently it has been shown that mismatch between the measurements electrodes might cause alterations on the EBIS measurements.
When performing EBIS measurements with textrodes certain
differences have been observed, especially at high frequencies,
respect the same EBIS measurements using Ag/AgCl
electrodes. In this work the influence of increasing the skinelectrode
area on the estimation of body composition
parameters has been study performing experimental EBIS
measurement. The results indicate that an increment on the
area of the skin-electrode interface did produce noticeable
changes in the bioimpedance spectra as well as in the body
composition parameters. This influence must be taken into consideration when designing and testing textile-enable EBIS measurement systems.
