  1. 1. Integrated Communications and Thermal Management Systems for Microsystem-based Spacecraft : A Multifunctional Microsystem Approach

    Author : Henrik Kratz; Anders Rydberg; Johan Köhler; Pelle Rangsten; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; nanospacecraft; MST; MEMS; silicon; communication; thermal management; antenna; paraffin; PCM; multifunctional; microsystems; Elektronik; Electronics; Elektronik;

    Abstract : This thesis explores the potential of multifunctional silicon-based microsystems for advanced integrated nanospacecraft (AIN). Especially, multifunctional microsystems with the coexistant functions of communications and thermal management implemented in multilayer silicon stacks are approached with systems study. READ MORE

  2. 2. Microsystem Interfaces for Space

    Author : Hugo Nguyen; Greger Thornell; Johan Köhler; Staffan Greek; Uppsala universitet; []
    Keywords : Engineering physics; microelectromechanical system; interface; microfluidics; nanosatellite; space; microsystems; filter; valve; MST; MEMS; Teknisk fysik;

    Abstract : 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. READ MORE

  3. 3. Modelling and Reliability Assessment of Microsystem Interconnections

    Author : Yan Zhang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cohesive zone model; discontinuous regularization; Micropolar theory; homogenization; microsystem interconnection;

    Abstract : 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. READ MORE

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

    Author : Jessica Melin; Göran Stemme; Sabeth Verpoorte; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; microsystem technology; pressure sensing; liquid manipulation; liquid control; micromixing; Mikrobiologi; Microbiology; Mikrobiologi;

    Abstract : 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

    Author : Johan Bejhed; Johan Köhler; Anders Eriksson; Greger Thornell; Thomas Laurell; Uppsala universitet; []
    Keywords : Engineering physics; microelectromechanical systems; MEMS; MST; microsystem; microfluidics; silicon; spacecraft; propulsion; space technology; Teknisk fysik;

    Abstract : 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.
