2. 16. Electrically Conducting Cellulose Yarns for Electronic Textiles

   Author : Sozan Darabi; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; electronic textiles; textiles; conjugated polymers; regenerated cellulose yarns; electrical properties; electrically conducting yarns; organic thermoelectrics;

   Abstract : Wearable electronics can be used for the purpose of fitness tracking, health monitoring, energy harvesting, and even for communication. Electronic textiles (e-textiles) are a versatile platform which can be employed for the realization of wearable electronics. READ MORE

4. 17. On the production of polyethylene dielectrics and conductive polymer composite fibres

   Author : Martin Strååt; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polyethylene; carbon black; polypropylene; melt spinning; foaming; polystyrene; fibres; cables; carbon nanotubes; electrical properties;

   Abstract : Foamed cable insulations and conductive polymer composite fibres are two applications in polymer processing where the electrical properties of a material may be altered significantly during processing. Their common denominator is that the outcome depends to a large degree on the flow behaviour of the polymer melt, in particular the melt extensional properties. READ MORE

5. 18. Geometrical controls on spectral induced polarization in time and frequency domain

   Author : Sara Johansson; Teknisk geologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spectral induced polarization; Microstructure; Electrical properties; Tomography; Multiscale;

   Abstract : What can we learn by transmitting electrical currents through electrodes in the ground? Geophysical methods can help us to locate the bedrock, valuable mineral ores, remains of ancient buildings and many other secrets hiding below the surface. However, it is not only the universal interest for the unknown that drives the geophysical research forward. READ MORE

7. 20. On the multifunctional performance of structural batteries

   Author : David Carlstedt; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modelling; Multifunctional composites; Electrical properties; Carbon fibre reinforced plastics; Mechanical properties; Energy storage;

   Abstract : The structural battery composite is a composite material that can store electrical energy (i.e. work as a battery) while simultaneously provide mechanical integrity in a structural system. Due to its inherent ability to store energy this material offers significant weight savings on a system level. READ MORE
