Microwave temperature measurement in microfluidic devices

Infrared Thermopile Temperature Measurement Technique in Microwave Heating Systems

Temperature measurement in microwave systems is essential for thermally driven processes, namely, catalytic reactions and ceramic sintering. Although, the application of direct thermometry methods, namely, thermocouples, have been commonly articulated in the available literature, however, contacted temperature measurement mechanisms have aroused concerns associated with the disruption of the el...

Microwave Dielectric Heating of Fluids in Microfluidic Devices

Microwave dielectric heating of drops in microfluidic devices.

We present a technique to locally and rapidly heat water drops in microfluidic devices with microwave dielectric heating. Water absorbs microwave power more efficiently than polymers, glass, and oils due to its permanent molecular dipole moment that has large dielectric loss at GHz frequencies. The relevant heat capacity of the system is a single thermally isolated picolitre-scale drop of water...

Improved Infrared Temperature Measurement of RF Devices

The paper describes the infrared (IR) thermal measurement facility at De Montfort University and the use of the facility to make IR temperature measurements on RF devices. Some of the limitations with conventional IR measurements will be described; including effects related to the low emissivity and optical transparency of materials. A novel method for improving the accuracy of IR temperature m...
