Abstract

Gas sensors working in the accumulating mode are suitable for direct amount and long-term detection of analytes in lowest concentrations. The applied sensitive materials are able to change at least one electrical property by the selective accumulation of analyte molecules. Few gas sensing devices, relying on the dosimeter-type sensing principle are described in the literature and most of them are mass sensitive, optical devices or field-effect transistors. The accumulating sensing principle was exemplarily investigated for a NOx storing material with very promising results.
