  4. 2. Microactuators for Powerful Pumps

    Author : Roger Bodén; Klas Hjort; Jan-Åke Schweitz; Johan Nilsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; µTAS; chromatography; high pressure; lab-on-a-chip; microactuator; microdispenser; micropump; on-chip; paraffin; PCM; point-of-care; Engineering physics; Teknisk fysik;

    Abstract : When paraffin wax melts it exhibits a large, relatively incompressible volume expansion. This can be used in microactuators for strong and large displacements, a rare combination among actuators. Furthermore, paraffin is inexpensive, inert and environmentally friendly, as well as easily processed and actuated. READ MORE

  5. 3. Miniaturized Multifunctional System Architecture for Satellites and Robotics

    Author : Fredrik Bruhn; Jan-Åke Schweitz; Lars Stenmark; Johan Köhler; Thomas George; Uppsala universitet; []
