SENSOR ARRANGEMENT AND METHOD FOR PRODUCING A SENSOR ARRANGEMENT

摘要

The present invention relates to a sensor arrangement (10) having a layer arrangement (12), wherein the layer arrangement (12) has a base layer (14), a middle layer (16) and a surface layer (18). The middle layer (16) is at least partially arranged on the base layer (14) and is in contact with same. The surface layer (18) is at least partially arranged on the middle layer (16) and is in contact with same. The base layer (14) and the surface layer (18) can make electrical contact for a conductivity measurement and/or a resistance measurement. The middle layer (16) is porous. The surface layer (18) is also porous and has an active measuring surface (20). The layer arrangement (12) has a non-planar alignment. A sensor arrangement (10) of this kind offers high sensitivity with high selectivity, even at ambient temperature, and can also be produced particularly inexpensively. The invention further relates to a method for producing a sensor arrangement (10). The present invention further relates to an analytical device comprising a sensor arrangement (10) and to use of a sensor arrangement (10) or an analytical device as a gas sensor in medical diagnostic evaluation, particularly in respiratory gas analysis.
