| Popis: | We set up in this work the evidence that an electronic nose system can be used for the noninvasive monitoring of human blood glucose since there is a direct correlation between acetone levels in exhaled breath and the blood glucose concentration. We designed and tested two types of gas sensors, and we present their features in order to develop an e-nose sensitive to the very low acetone concentration, and capable of discriminating the various interferences that may be present in human breath, and which may affect the measurements. In this study SnO2 and WO3 were used as gas sensing materials with a layer thickness of 50nm each, these layers have been deposited on silicon substrates containing platinum contact electrodes. Experimental test measurements and relevant data analyses have been conducted. |
