“…When greater complexity is required, electronic-circuit design becomes relevant. Our survey found 15 sources putting focus primarily on electrical signalling [13,23,24,38,44,45,65,67,69,85,86,92,93,114,132] and 15 other sources in which the signalling or wiring plays a major role [3,6,37,70,72,73,82,83,94,95,97,111,115,133,134]. Simple weave [23, 24, 65, 67, 70, 134] [82, 93, 94, 111, 132, 133] F-photodetector [16] F-temperature [16] Temperature and humidity [70] EL wire [56,121] LEDs [16] Capacitive yarn [16,50] PCB [132,133] F-biosensor [16] Optical fbre [42,98,105] Plate capacitor [129] Pressure sensor [16,…”

“…The insulation, which one must remove prior to soldering or other electrical connection, confers these wires' main beneftprevention of short circuits when the textile moves and yarns in its structure cross. Our review identifed use of Litz wire and other enamelled wires [44,45,72], plastic-insulated wire [23,24,65] and tinsel-wire [69], and wire-wrapped wire [67,82]. Litz wire, normally used for creating transformers and coils, consists of individually enamelled copper flaments bundled together.…”

“…From those electricalsignalling-oriented sources with clear discussion of attachment methods, we identifed several techniques. 1) Eleven pieces mention soldering the connections to the woven structure [6,44,45,69,85,86,94,95,111,133,134]. This method, which requires access to the electrical connection, uses heat to melt solder to connect the yarns together.…”

“…In the corpus's examples, inlay aforded creating fgurative colour-changing areas with yarns coated in thermochromic pigments [21,28], antenna structures [62], a moisture sensor [5], and a potentiometer embedded within a textile item woven with tapestry weave [124]. Somewhat resembling the inlay technique is serpentine lace, a method that has served the creation of fexible structure for signal traces [44,45]. Also, Huang et al [45] used tapestry weave for creating well-separated areas to form a 3D shape.…”

Advances to functional materials and fexible electronics have yielded new means of integrating electrical properties into textile materials, which invite researchers in various felds to apply woven-textile construction methods in eTextile development. However, common ground for woven eTextiles' prototyping is still taking shape. This calls for greater understanding of how the knowledge now scattered across diverse research felds can beneft the textiles' development for HCI. To investigate how eTextile research has employed weaving and extract insight for HCI purposes, the authors reviewed and categorised applications of woven structures and electrical functions, then identifed specifcally HCI-relevant qualities and means of creating them via weaving. The paper outlines those woven structures useful for HCI and advocates consistent weaving-related terminology, to improve knowledge transfer across disciplines. In addition, the results point to research opportunities involving haptic qualities, the ability to weave multiple layers, functionality integration, and tools and methods.

“…This enables creating custom garments, where material properties such as texture or elasticity can be fine-tuned dynamically [28,34]. Such material properties are essential for chronic deployment of wearable systems [24] both with regards to maintaining electrical functionality [23] and user comfort [38].…”

Electronic-embedded textiles or e-textiles preserve the form factor of typical apparel but have the ability to provide required electrical performance, enabling expanded functionality and comfort to the wearer. However, durable, reliable, and scalable manufacturing of e-textiles has remained one of the major challenges to large-scale development of garment-integrated applications of wearable technology. Moreover, there is a gap in our understanding of the impact of integration of electronics into textiles and challenges involved in manufacturing e-textile garments in mass. In this paper, we present the first manufacturing case study for electronic-embedded garments, to the best of our knowledge. We first developed a sensor-integrated fire-fighter turnout gear coat as an example e-textile product. Next, we performed a pre-production study to investigate the new variables that emerge from the prototyping phase to the production phase. To evaluate the challenges of manufacturing e-textiles in mass as compared to non-electronic garments, we produced forty pieces each of regular and temperature sensing fire-fighter turnout gear coat liner garments using stitched surface-mount fabrication methods. The study results show that the average manufacturing time and cost to produce a sensor-integrated thermal liner are 3.27 and 3.44 times higher, respectively, than producing a regular thermal liner garment, given that all the materials, labor, and standard sewing methods and machines remain constant. Additionally, we show the impact on requisite worker skills and training and quality assurance methods to produce e-textile garments compared to regular garments. We illustrate high-potential areas where strategic product and production design that leverages existing machines and tools can reduce the impact that embedded technologies have on labor, equipment, and cost. We conclude that the stitched surface-mount manufacturing method could potentially be used as an alternative for manufacturing e-textiles in mass.
