  • A novel Intelligent Textile technology based on silicon flexible skins
    Sensors and Actuators A-physical, 2008
    Co-Authors: Rakesh B. Katragadda, Y. Xu
    Abstract:

    This paper reports the successful prototype development of a novel Intelligent Textile technology based on the integration of silicon flexible skins with regular Textiles. This novel approach enables the embedding of sensing and computational components into Textiles without significantly compromising the flexibility and wearable properties. Silicon flexible skins comprised of arrays of silicon islands integrated with boron-doped strain gauges and metal pads were successfully fabricated using micromachining techniques. Prototypes of Intelligent Textiles were developed by stitching the silicon flexible skins onto the surface of Textiles. The preliminary tests demonstrated excellent durability of the prototypes. The strain experienced by the silicon islands was monitored in real-time using the integrated strain gauges when the prototypes were mechanically deformed. These strain data provide valuable information for the further optimization, and the next stage of development, of this Intelligent Textile technology.

  • Technical Embroidery for Smart Textiles: Review
    Materials Science. Textile and Clothing Technology, 2015
    Co-Authors: Viktorija Mečņika, Melanie Hoerr, Ivars Krievins, Stefan Jockenhoevel, Thomas Gries
    Abstract:

    Traditionally embroidery is known as a conventional technique of Textile decoration. Since the niche of technical Textiles is rapidly expanding and is the main field of innovation and research in Textile and apparel industry, embroidery is found in a variety of new functional applications due to the unique opportunity of creating three-dimensional light-weight structures and laying threads on the base material in all directions. As the field of smart Textiles is vast per se and is associated with technical Textiles and wearable technologies, the main applications of the embroidery may be described accordingly as ones for technical applications. In the sphere of medical Textiles, embroidery is a relatively new technique, but is successfully used for wound-dressing development and innovative solutions for tissue engineering due to the opportunity of creating three-dimensional structures from fine polymer materials. Another advantageous characteristic of goods developed by embroidery is dimensional stability of manufactured Textile structures. Due to these particularities embroidery is used widely also for such technical applications as development of heating grids, shielding, conductive interconnections, Intelligent Textile sensors and interfaces etc. Moreover, a large variety of materials and threads can be used in prototyping by the technique, e.g., conductive threads, metal wires, laminated polymer and carbon fibers. One of the challenging sub-sectors of Intelligent Textiles and smart Textiles for healthcare applications is the research and development of Textile sensors for biometrics and measurement of physical parameters. Most of the mentioned biosensors are implemented by transferring the principles of conventional actuators to the Textile structures.

  • Difunctional olefin block copolymer/paraffin form-stable phase change materials with simultaneous shape memory property
    Solar Energy Materials and Solar Cells, 2013
    Co-Authors: Qinglong Zhang, Jiachun Feng
    Abstract:

    Abstract In this work, a novel sort of form-stable phase change materials (FSPCMs) which possesses simultaneously the shape memory function was designed and prepared. The FSPCMs consist of paraffin with melting point of approximately 53 °C as a latent heat storage material and olefin block copolymer (OBC) as a supporting material. With mass percentage of paraffin up to 40 wt%, the FSPCMs exhibit good shape stability until temperature approaches 90 °C as shown by visual photographs, and this result is confirmed by dynamic mechanical analysis. At the same time, composites with 40 wt% paraffin also maintain the excellent mechanical property of OBC and exhibit large elongation at break as well as similar tensile stress, insuring excellent tenacity and deformation ability. The results of shape memory testing demonstrate that the composites possess good shape memory property, with nearly complete shape fixing and recovery. Compared with other reported FSPCMs, this material can be both temperature-controlled and temperature-sensitive, and may show advantages in some advanced applications such as Intelligent Textile. The diversity of paraffin endows the composites with flexibility of design for applications with wide range of temperatures. Considering the inexpensive sources and easy processing, this work may open up opportunities to produce difunctional FSPCMs in the industrial field.

  • Essential building blocks of fibrous tranSistors, part I: gate layer
    Advances in Science and Technology, 2012
    Co-Authors: Lina Rambausek, Bram Van Genabet, Anne Schwarz, Els Bruneel, Isabel Van Driessche, Lieva Van Langenhove
    Abstract:

    Abstract. During the last decade, research on Intelligent Textile systems progressed steadily. Today, science is focusing on full integration of electronics into Textiles. E-Textiles function like their rigid electronic companions but keep their Textile properties. To interconnect components within the system, Textile structures need to be equipped with electro-conductive properties. For flexible solar cells or fibrous transistors, electro-conductive coatings are applied. Transistors, acting as electrical switches, are essential for realizing fully integrated Intelligent Textile systems. By electroless deposition of pyrrole and copper on polyester fibres, conductivity is achieved. A DC conductive gate electrode is designed. In this paper, the development of the gate layer within the fibrous transistor is described. Ideal pH and optimal reaction time are determined as well as the effect of variation in fibre diameter is investigated. A reproducible polypyrrole layer has been obtained. Ideal reaction time was 180 minutes at a temperature of 278K. The electroless copper coating process on the polypyrrole layer showed optimal results when the substrate was immersed into the plating bath coated for 6 minutes at a pH of 13. Analysis through resistance measurements has been completed.

  • A Textile antenna for off-body communication integrated into protective clothing for firefighters
    IEEE Transactions on Antennas and Propagation, 2009
    Co-Authors: Carla Hertleer, Luigi Vallozzi, Hendrik Rogier, Lieva Van Langenhove
    Abstract:

    The introduction of Intelligent Textile systems to increase the wearer's level of protection has exposed the necessity of wearable communication tools and has led to research in Textile antennas. However, most Textile fabrics are quite thin (0.5 mm), making it challenging for antenna designers to provide an antenna which operates adequately and resiliently in the 2.4-2.4835-GHz industrial-scientific-medical bandwidth. Flexible pad foam is commonly available in protective clothing and overcomes these constraints by providing a uniform, stable, and sufficient thickness. Moreover, its cellular structure and properties, such as flame retardance and water repellence, make it an excellent substrate material for the integration of antennas into protective garments. In this paper, we describe the design, manufacture, and performance of the first Textile planar antenna to be implemented on flexible protective foam, suitable for firefighter garments. We employed shock absorbing foam with a thickness of 3.94 mm and achieved a nearly circularly polarized antenna with a bandwidth of more than 180 MHz even when the antenna was compressed or bent. These outstanding substrate and antenna characteristics result in an antenna that is highly appropriate for garment integration.

  • Wireless communication through a flexible antenna
    2009
    Co-Authors: Carla Hertleer, Lieva Van Langenhove, Hendrik Rogier
    Abstract:

    With the introduction of Intelligent Textile systems, the functionality of personal protective clothing is further enhanced. High tech fabrics protect the wearer from harsh environmental conditions, while monitoring systems provide information about his physical state during operation. Thus, a wireless communication device between the wearable system and an external base station is required. In order to allow maximum integration of this antenna into a garment, flexible Textile antennas have been introduced. In this work, a protective foam-based antenna for integration into a firefighter jacket is developed.
