Abstract: A monitoring system is disclosed that includes features for detecting the presence of biomarkers from a gas sample, such as exhaled breath. An assembly may also includes a plurality of sensors to detect biomarkers present in exhaled breath that are associated with respiratory illness. The biomarkers include carbon dioxide, carbon monoxide, and nitric oxide.

Abstract: A breath sensor (1) includes a heat exchange portion (41) that allows heat exchange between breath discharged from a second chamber C2 and breath introduced into a first chamber C1. Therefore, breath introduced into the first chamber C1 can be heated by breath discharged from the second chamber C2, to increase the temperature of the introduced breath. Since the temperature of the breath is increased, an effect of reducing power consumption of a heater (29c) in heating a conversion portion (21) and a detection portion (29a) is realized. The heater (29c) heats both the conversion portion (21) and the detection portion (29a) to a temperature in an operation or activation temperature range. Further, power consumption for heating to an operation temperature can be reduced by preheating the introduced breath as described above.

Abstract: A gas sensor including a plate-shaped base substrate and three or more mixed-potential-type sensor elements disposed at predetermined intervals on a main face of the base substrate and electrically connected in series. A single heat generation resistor for heating the mixed-potential-type sensor elements and a temperature sensor for measuring the temperature of the base substrate are embedded in the base substrate or disposed on a face of the base substrate opposite the main face. The heat generation resistor has a pattern which overlaps the mixed-potential-type sensor elements, and the maximum value of temperature differences among the mixed-potential-type sensor elements, produced as a result of energization and control of the mixed-potential-type sensor elements to a target temperature using the temperature sensor, falls within 5% of the target temperature.
