Abstract
The present work is a study of the thermal properties of integrable micro-filaments. The realised structure is the key element of the targeted integrable micro-pellistor for catalytic gas sensing, therefore, its thermal characterisation is of crucial importance. Direct measurement of temperature in the micro-heater is unfortunately troublesome due to the small dimensions used. In this work the temperature of the microfilament was measured by two different methods, based upon the resistance alteration of the filament, and analysis of the thermal radiation of the heated micro-filament. The reason for the differences was explained by inherent features of the methods, and confirmed by thermal simulation.
