| Description
| - This paper describes how thick-film technology was used to fabricate small, robust, sensitive, and selective semiconductor metal oxide (SMO) sensors to detect traces of ethanol vapours in air. The sensing parameters of several active layers were studiedincluding: sensitivity, response repeatability, stability and selectivity. The response to different species of five differently doped SnO2 sensors and a commercially available one were measured at concentrations between 1 ppb and 1000 ppm. Interaction wwas extremely high when ethanol came into contact with the Pt-doped SnO2 surface. The change in resistance of the Pt-doped sensors was between 2 and 55 times higher than the change in the commercial one. The Pt-doped SnO2 material is less resistant, more sensitive and shows faster response to ethanol than pure SnO2. Since the detection limit for ethanol is at sub-ppb level, the fabricated sensors could be used for alcoholmeters or for on-line monitoring and controlling the concentration of ethanol in fr

- Tato práce popisuje postup jak vytvořit malý, citlivý a selektivní senzor plynů s polovodivých oxidů kovů detekující etanol ve vzduchu. Byly studovány různé aktivní vrstvy, jejich citlivost, reprodukovatelnost odezvy, stabilita a selektivita. Odezva SnO2 senzoru dopovaného 5 různými materiály byla měřena pro koncetrace plynů v rozsahu 1 ppb až 1000 ppm. Pt-SnO2 senzor ukazuje větší citlivost, rychlejší odezvu a menší odpor vrstvy v parách etanolu než čistý SnO2. (cs)
