3. Oesophageal manometry : design and evaluation of measurement systems
Sammanfattning : 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. Paraffin Actuators in Microfluidic Systems
Sammanfattning : 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. LÄS MER
5. High-Pressure Microfluidics
Sammanfattning : 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. LÄS MER
