  1. 1. Silicon Carbide High Temperature Photodetectors and Image Sensor

    Author : Shuoben Hou; Mikael Östling; Carl-Mikael Zetterling; Per-Erik Hellström; Anthony O'Neill; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon Carbide SiC ; high temperature; photodetector; photodiode; phototransistor; ultraviolet UV ; transistor-transistor logic TTL ; bipolar junction transistor BJT ; integrated circuit IC ; pixel sensor; image sensor; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Silicon Carbide (SiC) has the advantages of ultraviolet (UV) sensing and high temperature characteristics because of its wide band gap. Both merits make SiC photodetectors very attractive in astronomy, oil drilling, combustion detection, biology and medical applications. READ MORE

  2. 2. SiC Readout IC for High Temperature Seismic Sensor System

    Author : Ye Tian; Carl-Mikael Zetterling; Ana Rusu; Philip A. Mawby; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon carbide SiC ; bipolar junction transistor BJT ; integrated circuit IC ; sigma-delta Σ∆ ; data conversion; operational amplifier OpAmp ; VBIC; SPICE Gummel-poon; high-temperature; electromechanical; accelerometer; capacitive sensor; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Over the last decade, electronics operating at high temperatures have been increasingly demanded to support in situ sensing applications such as automotive, deep-well drilling and aerospace. However, few of these applications have requirements above 460 °C, as the surface temperature of Venus, which is a specific target for the seismic sensing application in this thesis. READ MORE

  3. 3. Prostate cancer sensor : combining Raman spectroscopy and tactile resonance technology

    Author : Morgan Nyberg; Anders Eklund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical Engineering for Healthcare; Medicinsk teknik för hälsovård;

    Abstract : Prostate cancer (PCa) is the most common cancer type among men in Sweden. The most prevalent curative treatment for PCa is radical prostatectomy (RP), i.e., complete surgical removal of the prostate. READ MORE

  4. 4. Design and Performance of Diversity based Wireless Interfaces for Sensor Network Nodes

    Author : Magnus Jobs; Anders Rydberg; Shi Cheng; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless; Sensor; Network; WSN; Antenna; WISENET; Node; Diversity; Phased Array; Conformal; WBAN; Body Area; Engineering Science with specialization in Microwave Technology; Teknisk fysik med inriktning mot mikrovågsteknik;

    Abstract : The main focus of the work presented in this licentiate thesis concerns antenna design, adaptive antenna control and investigation on how the performance of small wireless nodes can be increased by inclusion of multiple antennas. In order to provide an end-user suitable solution for wireless nodes the devices require both small form factor and good performance in order to be competitive on the marked and thus the main part of this thesis focuses on techniques developed to achieve these goals.

  5. 5. Sensing capability of nanomodified Portland cement composites

    Author : Thanyarat Buasiri; Andrzej Cwirzen; Karin Habermehl-Cwirzen; Jan Olek; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensing cementitious composites; nanomodified Portland cement; Carbon nanofibers; CNF; piezoresistive materials; sensor; cement-based sensor; self-monitoring; sensing capability; Byggmaterial; Building Materials;

    Abstract : Sensing cement-based composites refer to composites that have sensing functionality that can measure several physical and chemical parameters. Sensing cement-based composites are fabricated by incorporating some functional fillers, such as conductive fibers (CFs), carbon nanofibers (CNFs), carbon nanotubes (CNTs), and graphene, into conventional concrete.
