摘要： The invention relates to a FET-based detector for carbon monoxide that is based on two sensitive layers (7, 8). The first of said sensitive layers (8) is catalytically active and thus react equally to alcohols, particularly ethanol, and carbon monoxide. The second of said sensitive layers (7) is not catalytically active and thus does not react to carbon monoxide, rather only to ethanol. From the comparison of the signals of both layers, the concentration of carbon monoxide can be determined. The two sensitive layers are implemented via similar metal oxide layers, wherein there is an additional layer having a catalyst such as palladium for the catalytically active layer. Alternatively, two different layers can be used, one of which is already catalytically active without an additional layer.

摘要： A method and a device for determining a physiological state of a test subject is presented. In the method, a first VOC pattern is determined from a first test medium and a second VOC pattern is determined from a second test medium. The first VOC pattern has a first group of VOCs and includes one or more VOCs detected in the first test medium and their respective concentrations. The second VOC pattern has a second group of VOCs and includes one or more VOCs detected in the second test medium and their respective concentrations. Subsequently, the first and the second VOC patterns are combined to obtain a VOCome pattern. Finally, the VOCome pattern is compared to a reference pattern. The reference pattern comprises a collection of different VOCs and concentrations of each of the different VOCs and represents a predicted known physiological state of the test subject.

摘要： The invention relates to a device and a method for determining the carbon dioxide content in air, for example for use in air conditioning systems. The gas sensor has a material that is sensitive to carbon dioxide as a gas-sensitive layer. Said material has a cross-sensitivity to air humidity. This is compensated for by measurement at two different temperatures. The measured gas values are calculated together, with the assumption that the sensitivity of the gas sensor to carbon dioxide exhibits a different curve with the temperature of the gas sensor than the sensitivity to water.

摘要： The invention relates to a method for operating a gas sensor for detecting nitrogen oxides in a gas mixture, comprising the following steps: provision of a gas sensor with at least two electrodes made from the same material and arranged on an oxygen ion conductor, wherein both electrodes contact the gas mixture during operation. A polarization of the electrodes is subsequently carried out in such a way that a voltage is changed from a first voltage to a second voltage.
