  3. 3. Oesophageal manometry : design and evaluation of measurement systems

    Author : Per Ask; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The aim of this study was to investigate the technical characteristics of oesophageal manometry systems and to improve the performance of these systems.The investigation of the characteristics of oesophageal manometry systems with non-perfused catheters or catheters perfused with a flow generated by a syringe pump did not show properties which fullfilled the requirements for accurate pressure measurements.

  4. 4. Paraffin Actuators in Microfluidic Systems

    Author : Marcus Lehto; Klas Hjort; Peter Woias; Uppsala universitet; []
    Keywords : Engineering physics; Paraffin; Actuators; Valve; Micropump; Teknisk fysik;

    Abstract : There is a need for reliable valves and pumps in microfluidics. A good microactuator is the key for low cost and high performance of these components.Paraffin wax is a promising material to be used as actuator material as is can produce large forces and large strokes. READ MORE

  5. 5. High-Pressure Microfluidics

    Author : Sam Ogden; Klas Hjort; Greger Thornell; Wouter van der Wijngaart; Uppsala universitet; []
    Keywords : phase change; actuator; valve; pump; supercritical fluid; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Abstract : In this thesis, some fundamentals and possible applications of high-pressure microfluidics have been explored. Furthermore, handling fluids at high pressures has been addressed, specifically by creating and characterizing strong microvalves and pumps.A variety of microstructuring techniques was used to realize these microfluidic devices, e.g. READ MORE
