Studying the chemiresistor platform properties

Popis výsledku v původním jazyce

In order to make a research of chemiresistors, having a suitable platform, on which studied layer can be created and measured is a necessity. Standard sensors are built upon ceramic base equipped with electrodes and heating or tempering elements. Here at Department of Physics and Measurements a transition to a KBI2 platform made by Tesla Blatna is being conducted. This particular model was chosen because at this time it is the only available one. Main purpose of this paper is mapping its properties, especially the homogeneity of temperature of the chip and overall its dynamic thermal properties. This platform was connected into the heating circuit and readouts of its internal temperature sensor (Pt-1000) were evaluated, the temperature was also observed using an thermal imager FLIR T 400 with a macro flyleaf. Calibration of thermal camera is also discussed as well, as determination of each area emissivity. The main result is description of temperature layout all over the chip of the platform and its step responses measured out of thermographical videos taken when the heating was switched on. These data can be further used as base for temperature regulation circuits design. Also quantification of uncertainties of the internal temperature sensor and temperature gradients, which cannot be neglected during sensor layer evaluation, is based upon these data. In the acquired data, symmetrical temperature layout by longitudinal axis is observed. Problems are seen in gradient over the chips length, for operating temperature 300 degrees C can this difference reach up to 100 degrees C.
