“…표 1에서 보는 바와 같이, 섬유에 도전성을 부여하기 위한 도전사(電導絲)의 사가공 기술은 은(Ag), 구리(Cu), 금(Au), 철(Fe) 등의 금속을 섬유 실올 표면에 금속 박막으로 피복하여 텍 스타일로서 활용하고 있다 [2]. 이와 같은 도전성 섬유의 전기 저 항치는 낮게 0.01Ω/m에서부터 수 Ω/m까지 분포하는데, 일반적으 로 도전사가 적용된 직물전극의 전기 저항치는 1~5 MΩ/cm 2 수준 에서 적용되고 있다 [3]. 국내외적으로 도전사의 전도성을 IT기술 과 융합시켜 활용한 텍스타일 제조 기술은 weaving, knitting, embroidering, printing 등의 다양한 직물 기법으로서 생체신호 감지용 직물전극을 통합화된 형태로 스마트 제품들에 적용하고 있 다 [4].…”

-In this study, the embroidery textile conductive wire of conductive yarn was designed into the wearable integrated clothing for sensing the infant's body temperature. To develop a high quality of the stable fiber-based textile conductive wire, firstly the five types of conductive yarns were twisted or covering polyester yarns and the coated conductive fiber with silver(Ag) or iron(Fe). As a result of comparative conductivity in conductive yarns of yarn processing, the 250 denier of conductive yarns with 0.74Ω/1~5cm were proposed and used for the integrated embroidery textile conductive wire for sensing. During experiments using the proposed embroidery textile conductive wire, measured resistance of thermistor according to the body temperature was correctly delivered to amplifier module, and showed feasible reliability of temperature sensing. As a wearable application, conductive yarns which takes forms of embroidery textile conductive wire would seems to be reliable as a conductive wire and could be replaced by the conductive metal wires.

“…In other cases, the electrodes were produced of textile materials, but separately from the suit/vest in which they would later be integrated by sewing or another joining process [6][7] [8]. Yet other researchers [9][10] produced fabrics in which the electrodes were knitted into the fabric itself, thus achieving a total integration with the textile.…”

This paper presents the results of a series of experiments aiming at the optimisation of vital sign monitoring using textile electrodes to be used in a swimsuit. The swimsuit will integrate sensors for the measurement of several physiological and biomechanical signals; this paper will focus on ECG and respiratory movement analysis. The data obtained is mainly intended to provide tools for evaluation of high-performance swimmers, although applications can be derived for leisure sports and other situations.A comparison between electrodes based on different materials and structures, behaviour in dry and wet environments, as well as the behaviour in different extension states, will be presented.The influence of movement on the signal quality, both by the muscular electrical signals as well as by the displacement of the electrodes, will be discussed. The final objective is the integration of the electrodes in the swimsuit by knitting them directly in the suit's fabric in a seamless knitting machine.

“…Several applications have benefited from the new textile electrode materials and wearable electronics [1]. They have enabled wearable monitoring of several physiological signals, also continuously and wirelessly [2][3][4][5][6]. In addition, monitoring and recording body postures and gestures has become more feasible, as textile materials allow a greater freedom of movement than the older recording systems [7,8].…”

Textile sensors, when embedded into clothing, can provide new ways of monitoring physiological signals, and improve the usability and comfort of such monitoring systems in the areas of medical, occupational health and sports. However, good electrical and mechanical contact between the electrode and the skin is very important, as it often determines the quality of the signal. This paper introduces a study where the properties of dry textile electrodes, textile electrodes moistened with water, and textile electrodes covered with hydrogel were studied with five different electrode sizes. The aim was to study how the electrode size and preparation of the electrode (dry electrode / wet electrode / electrode covered with hydrogel membrane) affect the measurement noise, and the skin-electrode impedance. The measurement noise and skinelectrode impedance were determined from surface biopotential measurements. These preliminary results indicate that noise level increases as the electrode size decreases. The noise level is high in dry textile electrodes, as expected. Yet, the noise level of wet textile electrodes is quite low and similar to that of textile electrodes covered with hydrogel. Hydrogel does not seem to improve noise properties, however it may have effects on movement artifacts. Thus, it is feasible to use textile embedded sensors in physiological monitoring applications when moistening or hydrogel is applied.
