    Sammanfattning : Melt Spun Piezoelectric Textile Fibres - an Experimental Study ANJA LUND Department of Materials and Manufacturing Technology Chalmers University of Technology ABSTRACT The manufacturing and characterisation of piezoelectric textile fibres are described in this thesis. A piezoelectric material is one that generates an electric voltage when deformed, a property which exists in a number of materials. LÄS MER

  3. 2. Electrochromism in Metal Oxide Thin Films : Towards long-term durability and materials rejuvenation

    Författare :Rui-Tao Wen; Claes-Göran Granqvist; Agustín R. González-Elipe; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrochromic; smart windows; long-term durability; degradation kinetics; ion trapping; de-trapping; materials rejuvenation; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Sammanfattning : Electrochromic thin films can effectively regulate the visible and infrared light passing through a window, demonstrating great potential to save energy and offer a comfortable indoor environment in buildings. However, long-term durability is a big issue and the physics behind this is far from clear. LÄS MER

  4. 3. Components of smart windows : Investigations of electrochromic films, transparent counter electrodes and sputtering techniques

    Författare :Lisen Kullman; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : In smart windows, the transmittance of visible and near infrared radiation can be reversibly and persistently modulatcd by an applied voltage pulse (~2 V). The micrometer-thick multi-layer structure contains two electrodes capable of charge insertion. One of these electrodes must be electrochromic; usually it consists of tungsten oxide. LÄS MER

  5. 4. Graphene : a vision to the future of smart E-Textile application

    Författare :Milad Asadi; Nawar Kadi; Priniotakis Georgios; Högskolan i Borås; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; graphene; graphene-coated e-textiles; catalyst immobilisation; hybrid graphene-catalyst multifunctional textiles; dye removal; e-textile; electro-Fenton; Fenton; wastewater treatment; Textil och mode generell ; Textiles and Fashion General ;

    Sammanfattning : Smart textile is a term referring to the textiles that could interact with their environment, receiving input and giving output based on their applications. Among smart textiles, electrically driven smart textiles (E-textiles) are being produced by various methods and materials integrated with textile substances. LÄS MER

  7. 5. Performance of Magnetorheological Rubber Materials

    Författare :Mattias Lokander; Bengt Stenberg; Vince Coveny; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; magnetorheological rubber; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Magnetorheological (MR) rubber materials are the solid analogue of magnetorheological fluids; i.e. their rheological properties can be controlled continously, rapidly, and reversibly by an applied magnetic field. LÄS MER
