“…As observed in [61], an article which gives an overview of the technologies concerning textile integrated sensors and electrodes for monitoring of biosignals (electrocardiographic-ECG and electromyographic-EMG, breathing and moisture), it is possible to integrate sensors and electrodes directly into the fabrics, which can be used in clothing for monitoring people in several conditions. Let us consider electrodes for instance.…”

Abstract:The polypyrrole, in its intrinsically conducting form, can be used to prepare composites such as polypyrrole/polyester textiles by coating yarns or fabrics made of polyester. In this manner, we obtain textiles that can be involved in several applications, among which we find the use of textiles in electromagnetic shielding. However, several other uses of polypyrrole/polyester composites are possible, such as in biomedical applications. Here we propose a survey of the literature about these composites. Keywords: Textiles, Polypyrrole, Intrinsically Conducting Polymers, Electromagnetic shielding IntroductionWhen opportunely processed, the polypyrrole becomes an intrinsically conducting polymer. This material can be used to prepare polypyrrole/polyester textile composites, by coating yarns or fabrics made of polyester. In this manner we obtain textiles that can be used for several applications. Two of them are the electromagnetic interference (EMI) shielding and the radiation-absorbent camouflage [1][2][3][4][5]. Materials for EMI shielding are needed due to the interference of radio frequency and microwave devices with computers, transformers, cables, mobile phones, medical devices, and also for the effect of the radiation on human health. Applications of textiles is therefore required for the shielding of persons, devices or large volumes such as those of an entire room. In the case that textiles are applied as radiation-absorbent materials they can be used in stealth technology, to disguise devices or structures from radar detection. Other applications of the polypyrrole/polyester fibres and fabrics are possible, in particular in the biomedical area.

“…To eliminate the uncomfortable feeling of the electrodes and cables, other methods using dry electrodes have been proposed [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. The electrodes and wires in such methods are made of conductive textile [1][2][3][5][6][7][8][9][10][12][13][14][15][16] or conductive ink [4,11], and are embedded in a shirt or belt. Such a shirt is called a smart shirt and the biological signals are measured for a person wearing the shirt [1][2][3][4][5][6][7][8][9].…”

“…The belt is wound around a subject's body and measures biological signals [10][11][12][13][14][15][16]. Smart shirts and belts measure various biological signals, including ECG signals [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16], electromyogram (EMG) signals [1,2,7,11], and signals of the respiration rate [1,7,[14][15][16] and other body properties [1,6,7,11,12,14,15]. We consider an ECG measurement made using smart shirts and belts.…”

“…Different methods of the ECG measurement employ bipolar leads, unipolar leads, standard limb leads, and unipolar precordial leads. Almost all existing smart shirts and belts adopt unipolar leads to measure the ECG signal, with the use of three electrodes being the simplest method [2][3][4][5][6][7][10][11][12][13][14][15][16]. Unipolar leads allow the measurement of the signal of a simple ECG signal but cannot be used to measure the signal of a detailed ECG.…”

Abstract:The Holter monitor is used to measure an electrocardiogram (ECG) signal while a subject moves. However, the Holter monitor is uncomfortable for the subject. Another method of measuring the ECG signal uses a smart shirt. We developed a smart shirt that has six electrodes on the chest and can measure a detailed ECG, obtained with unipolar precordial leads. The electrodes and wires of the shirt are made of conductive ink that is flexible and stretchable. The smart shirt is stretchable and fits the body well. However, because of the gap between the smart shirt and the body, electrodes V1 and V2 do not touch the body consistently. We developed a conductive foam block that fills this gap. We investigated the characteristics of the conductive foam block, and measured ECG signals using the smart shirt. The electrical resistance of the conductive foam block was reduced by pressure. This characteristic could be utilized to measure the ECG signal because the block was pressed by the body and smart shirt. We could measure the ECG signal using the smart shirt and blocks OPEN ACCESSFibers 2015, 3 464 while the subject walked and could detect peaks of the ECG signal while the subject jogged slowly.

Recent Progress and Perspectives of Thermally Drawn Multimaterial Fiber Electronics

Fibers are the building blocks of a broad spectrum of products from textiles to composites, and waveguides to wound dressings. While ubiquitous, the capabilities of fibers have not rapidly increased compared to semiconductor chip technology, for example. Recognizing that fibers lack the composition, geometry, and feature sizes for more functions, we set out years ago to explore the boundaries of fiber functionality. Our approach focused on a particular form of fiber production, thermal-drawing from a preform. This process has been used for producing single material fibers, but by combining metals, insulators, and semiconductors all within a single strand of fiber, an entire world of functionality in fibers has emerged. Fibers with optical, electrical, acoustic, or optoelectronic functionalities can be produced at scale from relatively easy-to-assemble macroscopic preforms. Two significant opportunities now present themselves. First, can we expect that fiber functions escalate in a predictable manner, creating the context for a "Moore's Law" analogue in fibers? Second, as fabrics occupy an enormous surface around our bodies, could fabrics offer valuable service to augment the human body? Towards answering these questions, we detail the materials, performance, and limitations of thermally-drawn fibers in different electronic applications and envision their potential in new fields.
