“…The current electrodes were always spaced 5 cm apart from the voltage electrodes. Placement 1 was chosen as it is a common electrode placement used by multiple different groups ( [4], [7] and [9]). Placement 2 was chosen to evaluate the impact of increased inter-electrode spacing.…”

“…Bioimpedance measurements for body composition/volume assessment were originally performed with electrodes placed on the wrist and ankle to measure the arm, trunk and leg in series. In recent years, bioimpedance has also been used for "segmental" measurements of smaller parts of the body such as joints [2], [3] and the calf [4], [5], [6], [7]. Shorter conductor lengths require a shorter interelectrode spacing, which prevents current from penetrating deep into the tissue.…”

Remote monitoring of fluid status via calf bioimpedance measurements could improve the experience of patients with congestive heart failure and reduce readmission rates. Most measurements today use conventional Ag/AgCl electrodes and a short inter-electrode spacing, resulting in current flowing primarily near the electrodes, preventing deeper current penetration and in turn accurate volume estimation. Textile band electrodes may more evenly distribute current throughout the calf. In the present study, simulations were conducted to investigate the impact of inter-electrode spacing/placement and fat tissue on bioimpedance using both Ag/AgCl electrodes and textile band electrodes. Simulation results showed that increasing the inter-electrode spacing can improve current distribution in the tissue, but there are still errors that increase with fat thickness (14.3% error at 10 cm spacing down to 1.7% error at 20 cm spacing for a "nominal" fat thickness, vs.-0.3% and-0.5% error for band electrodes). Band electrodes most closely matched the expected resistance and seem the most suitable regardless of inter-electrode spacing. Clinical relevance-This study suggests that band electrodes should be used for segmental bioimpedance measurements with short conductor lengths instead of spot electrodes.

“…A group of French researchers from Institute des Nanotechnologies de Lyon developed a device for home-based wireless segmental BIA measurement. Although patients with end-stage renal disease were primarily indicated as the potential target group, the proposed solution may prove beneficial in all patients requiring regular and objective monitoring of body fluid content [ 21 ]. The device may connect to a smartphone featured with a mobile app via Bluetooth [ 22 ].…”

Heart failure (HF) is a major clinical, social, and economic problem. In view of the important role of fluid overload in the pathogenesis of HF exacerbation, early detection of fluid retention is of key importance in preventing emergency admissions for this reason. However, tools for monitoring volume status that could be widely used in the home setting are still missing. The physical properties of human tissues allow for the use of impedance-based noninvasive methods, whose different modifications are studied in patients with HF for the assessment of body hydration. The aim of this paper is to present the current state of knowledge on the possible applications of these methods for remote (home-based) monitoring of patients with HF.
