  2. 11. Tactile sensing of prostate cancer : a resonance sensor method evaluated using human prostate tissue in vitro

    Author : Ville Jalkanen; Olof Lindahl; Britt Andersson; Tomas Jansson; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tactile resonance sensor; prostate tissue; prostate cancer; stiffness; density; elastic; variations; tissue histology; Medical engineering; Medicinsk teknik;

    Abstract : Prostate cancer is the most frequent type of cancer in men in Europe and the USA. The methods presently used to detect and diagnose prostate cancer are inexact, and new techniques are needed. READ MORE

  4. 12. Autonomous Lab-on-a-chip: solutions and fast prototyping tools

    Author : German Comina Bellido; Daniel Filippini; Edwin Jager; Anke Suska; Niels B. Larsen; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous Lab-on-a-chip; bio-chemical sensing; sensor fabrication; biosensing cell phone; 3D printed fluidics; 3D printed optics.;

    Abstract : In this thesis, solutions for the development of autonomous Lab-on-a-chip (LOC), and 3D printing for fast prototyping of LOC devices are investigated. Lab-on-a-chip devices integrate analytical systems and conditioning processes in a compact package. READ MORE

  5. 13. Durability of Embedded Fibre Optic Sensors in Composites

    Author : Klas Levin; KTH; []
    Keywords : composites; fibre optic sensor; embedded EFPI sensor; bragg grating sensor; durability. Fatique; impact strain measurement;

    Abstract : This thesis concerns various aspects of the durability offibre optic sensors embedded in composite. Since repair orreplacement of embedded sensors is not generally possible, thefunctional reliability of embedded sensors is one of the mostimportant prerequisites for successful use. READ MORE

  6. 14. 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. 15. Polymer-Nanoparticle Hybrid Materials for Plasmonic Hydrogen Detection

    Author : Iwan Darmadi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; hydrogen; nanofabrication; hybrid material; nanocomposite; polymer; alloy; sensor; nanoplasmonic; palladium;

    Abstract : Plasmonic metal nanoparticles and polymer materials have independently undergone rapid development during the last two decades. More recently, it has been realized that combining these two systems in a hybrid or nanocomposite material comprised of plasmonically active metal nanoparticles dispersed in a polymer matrix leads to systems that exhibit fascinating properties, and some first attempts had been made to exploit them for optical spectroscopy, solar cells or even pure art.
