Abstract :
Thermal aspects of the design and fabrication of sensor structures based on thermally isolated heater filaments (Ducso, Cs. et al., Sensors and Actuators, vol.A60, p.235-9, 1997) were investigated with special attention to their dynamic properties. Thermal engineering was aided by high performance simulation methods, such as finite element modelling (COSMOS) and thermal equivalent circuit simulation using successive network reduction (SUNRED) method. The detailed static and dynamic thermal behaviour of the structure was experimentally characterised applying the high resolution thermography system of Thermosensorik GmbH and the thermal transient tester (T3Ster) of MicReD Ltd.
