  • Abstract
    A solid-state potentiometric CO2-sensor of the type CO2, O2, Au, Li2CO3-BaCO3 | Nasicon | Na2Ti6O13-TiO2, Au, O2, CO2 was fully manufactured in planar thick-film technology. Due to an integrated screen-printed heater on the rear side, the sensor can be applied in a small tube for breath analysis, despite its high working temperature of 525°C. The sensor is insensitive to variations of the oxygen partial pressure and follows strictly the Nernst equation. Based on this behavior, the presented sensor cell is suitable for exhale air analysis.
