Abstract

In mobile health monitoring systems, particularly wearable electronic systems (WES), bio-signals measuring tools embedded in clothing becomes a viable alternative. Such an alternative is usually designed using flexible conductive media that can capture and transmit bio-signals while maintaining signal reliability and biocompatibility. In addition, WES products are effectuated by the emergence of conductive threads as an appropriate electrical medium for health monitoring through wearable garments. To accomplish this task, conductive threads are emerging as an appropriate electrical medium for bio signals monitoring. Therefore, the conductive thread is to be considered as a key factor in designing and manufacturing textile-based electronics. However, the behavior of conductive threads under different sewing parameters has been studied to obtain high-quality bio-signals. In this paper herein the impact of electrically conductive properties of specific conductive threads under three conditions was studied; (a) as sewn configurations on different types of weft knitted fabric substrates, (b) as sewn configurations with different stitch types, and (c) as working independent threads under various parameters of the sewing process. The purpose of this study is an attempt to design and attach conductive paths to the surface of different fabrics, integrating wearable sensors and electronic elements with those paths to produce smart sleeves capable of monitoring electromyogram (EMG) signals. In addition, our research work could be considered as a comprehensive study to analyze both of electrical performance and behavior of the conductive threads under several sewing conditions for different types of weft knitted fabrics. The expected results can help in developing final products of textile-based electronics to confront the functional and aesthetic performance of consumer’s acceptance. Experimental results show that both sewing and fabric parameters significantly influenced the electrical resistance of sewn transmission lines. In addition, the quality of the acquired and transmitted Abstract IV bio-signals has been consequently affected. In fact, improper resistance of high transmission lines and/or paths would result in poor bio-signal quality. Therefore, one must admit that our study is of the utmost importance for the design of effective stitched transmission lines, manufacture of Wearable Electronic Products (WEP), and then consequently monitoring of bio-signals. To that end, the study proposes designing a smart sleeve that will provide readings on the position of the EMG signals captured with sewn transmission lines, which will be compared to the intended movement derived from the EMG signals captured with standard cables. In order to evaluate these paths, signals will be recorded, processed, and evaluated by using the MATLAB program.
