[Advances in Intelligent Systems and Computing] Artificial Intelligence on Fashion and Textiles Volume 849 (Proceedings of the Artificial Intelligence on Fashion and Textiles (AIFT) Conference 2018, Hong Kong, July 3–6, 2018) || Woven Light: An Investigation of Woven Photonic Textiles
摘要： Textile materials, which have been widely used in apparel, interior design, health care, automobile, and infrastructure, play a fundamental role and exhibit a close relationship to human’s daily life. For the past few decades, smart textile materials with new performance, functionality, and design values have been developed through the integration of advanced technologies [1]. This study aims to review and examine current approaches to realize photonic textiles, including LED-embedded, photoluminescent, and polymeric optical fiber (POF) textiles. This work also reviews examples of woven interactive textiles and discusses how weave parameters can affect POF textiles. POF textiles, which exhibit the advantage of directly incorporating functional fibers during the fabrication process, have the potential to serve as a flexible textile display. In addition, this material provides high design values due to its dynamic visual appearance. One of the fabrication methods used to produce POF textiles is the weaving technique. The properties of smart textiles, including hand feel, elasticity, flexibility, and drapability, can be considerably changed through the interplay among weaving variables, such as fiber content, patterns, weave structures, fabric construction, and finishing techniques. Complex woven structures can be designed to simplify the production process; novel yarns can be used to provide variety to textile appearance and tactility. However, few studies have been conducted on the fabrication process of smart textiles through weaving. Tan and Bai developed prototypes of interactive cushions using POF textiles integrated with touch sensors [2, 3]. The design process of these prototypes focuses on the integration of electronic components and interactivity instead of on the textile fabrication method. A literature review indicates that research on the weaving structures of POF textiles is lacking. The use of weaving techniques to create innovations for smart textiles to enhance their appearance, performance, and functionality demonstrates potential.

Elaboration of a Conductive Textile by Coating for Clothes Equipped with Fourth-Generation Photovoltaic Cells
摘要： Conducting polymer coated in textiles possess a wide range of electrical properties. The surface resistivity is influenced by concentrations of the reactants, thickness of the coating, nature of the substrate surface, extent of penetration of the polymer into the textile structure and the strength of the binding of the coating to the textile surface. Low resistivity in fabric results from highly doped thicker coatings that penetrate well into the textile structure thus enabling good electrical contact between fibers. In this study, we had chosen copper as conductor polymer for coating. The electrical conductivity is influenced by the thickness of coating paste, the nature of the substrate surface. The thickness of the paste and the concentration of the copper were studied in this paper. Furthermore, the electrical surface resistance decreased from 68 MΩ to 8 MΩ with decreasing in coating thickness. However, the thickness of coated fabric is very important factor to determine conductivity and application of textile. In addition, we had noticed that the airflow is affected by the coating thickness which the penetration of the airflow differs from the lower thickness to the higher one. This study confirm that we can use coating woven fabric to develop a textile substrate responding to characteristics such as electrical resistance, drapability, air permeability and tensile strength, which are particularly important to be used as a support for flexible photovoltaic cells in clothes.

Encapsulated Textile Organic Solar Cells Fabricated by Spray Coating
摘要： Solution based processes such as screen printing and spray coating are established processes for fabricating organic solar cells (OSCs) on flexible polymer substrates. However, realizing a flexible solar cell on a textile substrate remains a significant challenge due to the properties of the textile itself, which can present an absorbent, rough and fibrous surface. The textile also limits processing temperatures which can reduce functional materials performance. In this work, we demonstrate an optimized fabrication approach using entirely spray coating to fabricate textile OSCs with a power conversion efficiency (PCE) of 0.4 %. An interface layer is first deposited on the standard woven textile that forms a smooth supporting layer for the subsequent spray coated functional layers. A top encapsulation layer is deposited on top of the fabricated textile OSCs, which improves the durability and life time of the OSCs is evidenced by cyclic bending test.

Facile fabrication of phosphorus-doped g-C3N4 exhibiting enhanced visible light photocatalytic degradation performance toward textile dye
摘要： Phosphorus-doped graphitic carbon nitride (P-g-C3N4) was facilely fabricated by in situ thermal copolymerization of urea and triphenylphosphine source materials. The P-g-C3N4 exhibited an enhanced photocatalytic performance than pristine g-C3N4 counterpart for the degradation of rhodamine B and acid blue D-2BR textile dye under visible light irradiation. X-ray diffraction (XRD), transmission electron microscopy (TEM), N2 adsorption-desorption isotherms, X-ray photoelectron spectra (XPS), and diffuse reflection spectroscopy (DRS) techniques were used to characterized the structure and property of P-g-C3N4 photocatalyst. The phosphorus doping enhanced visible light harvesting and surface area, but also substantially changed the electronic property of g-C3N4 material that could suppress the recombination of photogenerated charge carriers, and thus improved photocatalytic performance.

Self-Powered Motion-Driven Triboelectric Electroluminescence Textile
摘要： In recent years, smart light emitting type electronic devices for wearable applications have been required to have flexibility and miniaturization, which limits the use of conventional bulk batteries. Therefore, it is important to develop a self-powered light emitting system. Our study demonstrates the potential of a new self-powered luminescent textile system that emits light driven by random motions. The device is a ZnS:Cu based textile motion-driven electroluminescent device (TDEL) fabricated onto the woven fibers of the ZnS:Cu embedded PDMS (Polydimethylsiloxane) composite. Triboelectrification, which raises a discontinuous electric field, is generated by the contact separation movement of the friction material. Therefore, light can be generated via triboelectrification by the mechanical deformation of the ZnS:Cu embedded PDMS composite. This study showed that the TDEL emitted light from the internal triboelectric field during contact and from the external triboelectric field during separation. Light was then emitted twice in a cycle, suggesting that continuous light can be emitted by various movements, which is a key step in developing self-powered systems for wearable applications. Therefore, this technology is a textile motion-driven electroluminescence system based on composite fibers (ZnS:Cu + PDMS) and PTFE fibers, and the proposed self-emitting textile system can be easily fabricated and applied to smart clothes.

[IEEE 2018 IEEE International Conference on RFID Technology & Application (RFID-TA) - Macau, Macao (2018.9.26-2018.9.28)] 2018 IEEE International Conference on RFID Technology & Application (RFID-TA) - Fabrication and Practical Evaluation of Glove-integrated Passive UHF RFID Tags
摘要： Passive RFID-based technology is a convincing approach to achieve versatile energy- and cost-efficient wireless platforms for future wearable applications. In this paper, we present passive UHF RFID tags integrated into normal work gloves for wearable RFID applications. We introduce embroidery as a new efficient antenna fabrication method for glove-integrated tags as well as establish reference glove-tag antennas from electro-textiles and copper tape. The performance of the three types of glove-tags is evaluated on a male test subject in an anechoic room and in an office environment. Based on the wireless measurement results, the read ranges of the embroidered glove-tags were around 1 meter in an anechoic chamber and in an office, when measured near the human body. These results meet the requirements of many practical applications of glove-tags, although the read ranges are shorter than those of the electro-textile and copper tape tags that showed read ranges of 2-2.5 meters. Finally, the developed glove-tags were successfully tested in actual use situations for identification and access control. These results are very promising, especially considering the cost-effectiveness of embroidered tag antennas and the easiness of their integration into different types of gloves.

A Novel Flexible Electro-textile 3T MRI RF Coil Array for Carotid Artery Imaging: Design, Characterization and Prototyping
摘要： Magnetic Resonance Imaging (MRI) is one of the most powerful imaging modality in clinics and is essential for the diagnosis of strokes through carotid artery imaging. The limiting factor for high quality MR imaging is the Signal to Noise Ratio (SNR) performance of the Radio Frequency (RF) coils. The current RF surface coils, however, are made of rigid materials or semi-flexible materials with very limited bending properties. As a result, their SNR is limited because they cannot be placed very close to the imaging area thus receiving noises from parts of the human body that are not intended to be imaged. Taking advantage of the computerized embroidery and laser cutting technology, in this work, we utilize electro-textile to design, fabricate and measure multi-layer RF coil array system for 3T MRI to improve the SNR performance. The proposed RF coil array system provides an ergonomic and high performance solution to the 3T MRI systems. A roadmap to systematically design electro-textile RF coil arrays is proposed. RF coil array is characterized to have the accurate resonant frequency, good impedance matching, and low mutual coupling. Additionally, magnetic field distribution, bending effects, human body effects are also discussed. A systematic method to characterize the performance of the electro-textile pattern is studied and used to assist the development and performance characterization. Finally the high resolution and high SNR images of various kinds of phantoms are obtained using the UCLA Antenna Lab electro-textile coil array after its integration with the 3T MRI scanners at UCLA David Geffen School of Medicine Translational Research Imaging Center (TRIC). Compared with the conventional surface coil, more than 10 dB SNR increase is observed at the depth of 0.5 cm and 3 dB increase at the depth of 3 cm.

Photovoltaic Potential Assessment and Dust Impacts on Photovoltaic Systems in Iran: Review Paper
摘要： Smart-fabric interactive-textile systems offer exciting new possibilities, provided that they exhibit sufficient robustness and autonomy to be reliably deployed in critical applications. Textile multiantenna systems, unobtrusively integrated in a professional garment, are key components of such systems, as they set up energy-efficient and stable wireless body-centric communication links. Yet, their functionality may be further extended by exploiting their surface as energy-harvesting platform. Different state-of-the-art energy harvesters are suitable for compact integration onto a textile antenna. We demonstrate this by integrating a power management system, together with multiple diverse scavenging transducers and a storage module, on a well-chosen textile antenna topology. We provide guidelines to ensure that the additional hardware does not affect the textile antenna’s performance. Simultaneous scavenging from different energy sources significantly increases the autonomy of a wearable system, in the meanwhile reducing battery size.

Graphene Boosted Silver Nanoparticles as Surface Enhanced Raman Spectroscopic Sensors and Photocatalysts for Removal of Standard and Industrial Dye Contaminants
摘要： Uncontrolled volumes of textile effluents (TE) discharged into water-bodies significantly escalate the possibility of health hazards and environmental deterioration owing to the presence of hazardous dye contaminants. In this work, the toxic components in real TE were sensed on a graphene boosted silver nanoparticles (Ag-rGO) platform through surface enhanced Raman scattering (SERS) technique. Transmission electron microscopic images of Ag-rGO showed spherical Ag nanoparticles of ~8 nm dispersed on wrinkled graphene oxide sheets. The efficiency of the substrate as a SERS sensor and photocatalytic substrate was first analyzed on commercial dyes such as rhodamine6G, Congo red and malachite green. In TE, carcinogenic azo dye contaminants were effectively identified from the presence of N=N and C-N bands present in the SERS spectra. Further, removal of these dye contaminants in TE through visible light assisted photocatalysis by Ag-rGO was also evaluated. High degradation rate constant of ~9 x 10-3/min was observed in TE after visible light assisted photocatalysis by Ag-rGO. Synergistically, the dual utility of Ag-rGO can be attributed to the enhanced electromagnetic field originating from the plasmonic nature of Ag nanoparticles and the strengthened charge transfer due to the adsorptive nature of rGO. Furthermore, the reduced particle size and suppressed fluorescence also aids the sensing and removal. These results suggest feasible development of sensitive, scalable, stable intermediate dye sensing and removal/ water recycling structures based on Ag-rGO to be incorporated at the discharge stage of textile dyeing industries.

Laser-Writing of Janus Graphene/Kevlar Textile for Intelligent Protective Clothing
摘要： Protective clothing plays a vital role in safety and security. Traditional protective clothing can protect human body from physical injure. It is highly desired if modern wearable electronics can be integrated into traditional protection suit to endow it with versatile smart functions. However, it is still challenging to integrate electronics into clothing through a practical approach while keeping the intrinsic flexibility and breathability of textiles. In this work, we realized the direct writing of laser-induced graphene (LIG) on Kevlar textile in air and demonstrated the applications the as-prepared Janus graphene/Kevlar textile in intelligent protective clothing. The C=O and N?C bonds in Kevlar were broken and the remaining carbon atoms were reorganized into graphene, which can be ascribed to photothermal effect induced by the laser irradiation. Proof-of-concept devices based on the prepared graphene/Kevlar textile, including flexible Zn-air batteries, electrocardiogram electrodes, and NO2 sensors, were demonstrated. Furtherly, we fabricated a self-powered and intelligent protective clothing based on the graphene/Kevlar textile. The laser induced direct writing of graphene from commercial textiles in air conditions provides a versatile and rapid route for the fabrication of textile electronics.
