  2. 2. Microsystem Interfaces for Space

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Hugo Nguyen; Uppsala universitet.; [2006]
    Nyckelord :Engineering physics; microelectromechanical system; interface; microfluidics; nanosatellite; space; microsystems; filter; valve; MST; MEMS; Teknisk fysik;

    Sammanfattning : Microsystem interfaces to the macroscopic surroundings and within the microsystems themselves are formidable challenges that this thesis makes an effort to overcome, specifically for enabling a spacecraft based entirely on microsystems. The NanoSpace-1 nanospacecraft is a full-fledged satellite design with mass below 10 kg. LÄS MER

  3. 3. Modelling and Reliability Assessment of Microsystem Interconnections

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Yan Zhang; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cohesive zone model; discontinuous regularization; Micropolar theory; homogenization; microsystem interconnection;

    Sammanfattning : With the continuous increase of packaging density, the electronic component size and, in particular, the thickness of the involved interconnections decrease significantly. In addition, the microsystem interconnects usually include even finer internal structures. LÄS MER

  4. 4. Novel Microsystem Techniques for Liquid Manipulation and Pressure Sensing

    Detta är en avhandling från Stockholm : Signaler, sensorer och system

    Författare :Jessica Melin; KTH.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microbiology; microsystem technology; pressure sensing; liquid manipulation; liquid control; micromixing; Mikrobiologi; NATURAL SCIENCES Biology Organism biology Microbiology; NATURVETENSKAP Biologi Organismbiologi Mikrobiologi;

    Sammanfattning : Scaling down operations and functions into the fascinating micro world not only improve performance, lower costs, and enable easier integration, but also opens the door to new functionalities. This truly multidisciplinary thesis presents novel solutions to current and relevant challenges in the areas of 1) on-chip liquid manipulation which has applications in micro total analysis systems, medical diagnostics, and drug discovery and 2) pressure sensing which has an established market in the automotive and industrial processes industry.

  5. 5. Fluidic Microsystems for Micropropulsion Applications in Space

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Johan Bejhed; Uppsala universitet.; [2006]
    Nyckelord :Engineering physics; microelectromechanical systems; MEMS; MST; microsystem; microfluidics; silicon; spacecraft; propulsion; space technology; Teknisk fysik;

    Sammanfattning : Spacecraft on interplanetary missions or advanced satellites orbiting the Earth all require propulsion systems to complete their missions. Introducing microelectromechanical systems technology to the space industry will not only reduce size and weight of the propulsion system, but can also increase the performance of the mission. LÄS MER
