    Abstract : 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. READ MORE

  2. 2. Conducting Foams and Fibres for Bulk Plastic Thermoelectrics

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Jason Ryan; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nanocomposites.; e-textiles; renewable energy; conducting yarn; thermoelectrics; conjugated polymers; organic thermoelectrics; electronic textiles; polymer foams; conducting fibres;

    Abstract : The use of small portable electronics in society is constantly increasing, thus the demand for portable power sources also rises in turn. Portable electronic devices rely upon energy stored in batteries to power them, which in turn require regular access to power outlets to be recharged. READ MORE

  3. 3. Exploring fully integrated textile tags and information systems for implementing traceability in textile supply chains

    University dissertation from Borås : Högskolan i Borås
