    Abstract : Cu nanoparticles are commonly used in microelectronic devices and as catalysts in, for example, methanol synthesis and methanol steam reforming reactions. However, Cu nanoparticles are prone to oxidation. READ MORE

  4. 7. Fibre-Optic Displacement and Temperature Sensing Using Coupling Based Intensity Modulation and Polarisation Modulation Techniques

    Author : Johan Jason; Hans-Erik Nilsson; Bertil Arvidsson; Werner Daum; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical fibre sensor; displacement measurement; temperature measurement; fibre coupling; intensity modulation; birefringence; polarisation; OTDR; side-hole fibre;

    Abstract : Optical fibre sensors are employed in the measurements of a number of different physical properties or for event detection in safety and security systems. In those environments which suffer from electromagnetic disturbance, in harsh environments where electronics cannot survive and in applications in favour of distributed detection, fibre-optic sensors have found natural areas of use.

  5. 8. Printed RFID Humidity Sensor Tags for Flexible Smart Systems

    Author : Yi Feng; Werner Zapka; Li-Rong Zheng; Qiang Chen; Donald Lupo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intelligent packaging; humidity sensor; wireless sensor; chipless RFID; multi-walled carbon nanotube; inkjet printing; LC resonator; paper electronics; flexible electronics.;

    Abstract : Radio frequency identification (RFID) and sensing are two key technologies enabling the Internet of Things (IoT). Development of RFID tags augmented with sensing capabilities (RFID sensor tags) would allow a variety of new applications, leading to a new paradigm of the IoT. READ MORE

  6. 9. Theory and Applications of Coupling Based Intensity Modulated Fibre-Optic Sensors

    Author : Johan Jason; Hans-Erik Nilsson; Bertil Arvidsson; Bernt Sundström; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fibre-optics; sensor; intensity modulation; coupling; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : Optical fibre sensors can be used to measure a wide variety of properties. In some cases they have replaced conventional electronic sensors due to their possibility of performing measurements in environments suffering from electromagnetic disturbance, or in harsh environments where electronics cannot survive.

  7. 10. Organic electronics for precise delivery of neurotransmitters

    Author : Amanda Jonsson; Magnus Berggren; Daniel Simon; Marco Rolandi; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Organic electronic materials, that is, carbon-based compounds that conduct electricity, have emerged as candidates for improving the interface between conventional electronics and biological systems. The softness of these materials matches the elasticity of biological tissue better than conventional electronic conductors, allowing better contact to tissue, and the mixed ionic-electronic conductivity can improve the signal transduction between electronic devices and electrically excitable cells.
