| Research Abstract |
This study aimed to develop a new method for measuring thermal conductivity of gases and liquids using a micro-beam MEMS sensor that is suspended across a trench on a silicon substrate. In this method, the thermal conductivity of a sample is determined by measuring the temperature of the sensor at a steady-state after heating it in a sample fluid. After developing the fabrication process, feasibility of the method was demonstrated by comparing the results between the air and FC-72 as test fluids using platinum and gold sensors approximately 10 μm in length. The fact that the temperature rise of the sensor does not depend on the flow was also demonstrated by an experiment in an external air flow, which is important for the application of the sensor as gas sensors.
