Recently, it has been shown that the degree of loading of several types of automotive exhaust aftertreatment devices can be directly monitored in situ and in a contactless way by a microwave-based method. The goal of this study was to clarify whether

Very often, high-temperature operated gas sensors are cross-sensitive to oxygen and/or they cannot be operated in oxygen-deficient (rich) atmospheres. For instance, some metal oxides like Ga2O3 or doped SrTiO3 are excellent materials for conductometr

In order to meet the future emissions regulations, nitrogen oxides (NO x ) sensors with a high sensitivity in the low ppm detection range will be required. An integrating NO x sensor concept is proposed for that purpose. In this concept, well-known l

To control or monitor processes and the compliance with air quality regulation, highly selective and long‐term stable gas sensors with a high accuracy in the low ppm detection range are needed. Gas sensor techniques detecting the actual concentrati

The accumulating gas sensor principle is a promising concept to measure selectively low amounts of an analyte. Hereby, the change of the electrical properties of an analyte storage material serves as sensor signal. In earlier approaches, the sensor s
