“…The relatively wide range of resistance values is needed for samples intended for textile-based sensor such as strain sensors [3] or temperature sensors [4]. Fixed values at a certain level are required for flat textile products intended for the manufacture of medical electrodes [5], electromagnetic interference shielding textiles [6] or textiles conveying electrical signals [1,2]. It means that the product is stable in working conditions.…”

Woven and knitted fabrics were chosen to determine their electro-conductive properties. Van der Pauw equation modified by Wasscher for anisotropic materials was used. The electrical conductivity of textile materials was anisotropic as indicated by the biaxial anisotropy coefficient being in the range from 1.1 to 7.2. Resistance was higher when current flows between electrodes arranged on the line parallel to the warp and course direction in the case of woven or knitted fabrics respectively. Results of analysis confirmed the effect of sample surface roughness on its electro-conductive properties. Sample with a smooth surface will conduct electrical current better than sample with a rough one. Electrical resistivity of the fabrics indicated that they can be used as paths for conveying electrical signals.

“…Each subject was tested under the standard conditions between 4:00 pm and 10:00 pm at temperatures of [21][22][23][24][25][26] ∘ C after refraining from smoking and coffee utilization for six hours before his/her contribution to the experiment. The investigated properties of ECGs and basis of evaluation can be viewed in Table 2.…”

“…Such electrodes were compared with commercial Ag/AgCl electrode for the performances in terms of electrode position, cleaning, signal quality, spin supplies, and repeatability. Zieba et al [22] discussed a textronic knitting method that is integration of biosensors and measurement prototype within knitting patterns. The knitted fabric was used in their work, and the platform for ECG monitoring was based on three-electrode method.…”

Long-time monitoring of physiological parameters can scrutinize human health conditions so as to use electrocardiogram (ECG) for diagnosis of some human's chronic cardiovascular diseases. The continuous monitoring requires the wearable electrodes to be breathable, flexible, biocompatible, and skin-affinity friendly. Weave electrodes are innovative materials to supply these potential performances. In this paper, four conductive weave electrodes in plain and honeycomb weave patterns were developed to monitor human ECG signals. A wearable belt platform was developed to mount such electrodes for acquisition of ECG signals using a backend electronic circuit and a signal transfer unit. The performance of weave ECG electrodes was evaluated in terms of skin-electrode contacting impedance, comfortability, ECG electrical characteristics, and signal fidelity. Such performances were then compared with the values from Ag/AgCl reference electrode. The test results showed that lower skin-electrode impedance, higher R-peak amplitude, and signal-to-noise ratio (SNR) value were obtained with the increased density of conductive filaments in weave and honeycomb weave electrode presented higher comfort but poorer signal quality of ECG. This study inspires an acceptable way of weave electrodes in long-and real-time of human biosignal monitoring.

“…Due to the new use of electrically conductive textiles, e.g. electrodes to muscle electrical stimulation [6], it is important to uniform distribution of the resistance measured between any points on the surface of the sample. The authors have proposed a new approach for measuring the resistance of the flat textile of electroconductive properties.…”

The main purpose of the study was to present the basic problems of determining surface resistance of electroconductive fabric. The attention was paid to the arrangement of electrodes on a sample. Analysis of the contact resistance between the measuring electrode and the fibrous substrate was conducted. The multi-variant research of a textile sample has shown that the electrodes arrangement is of significance for sample resistance measurement results. The arrangement of four electrodes on the edge of the sample allows the assessment of electroconductive properties of whole textile sample surface. It was found that the woven fabric sample is not homegeneous and anisotropic. Research of textile material with the coaxial electrode arrangement enable the local values of material resistance to be assessed. Results of multi-variant research have provided important knowledge about the textile material structure and its properties.
