A sensor, which can be designed in particular as a capacitive soot sensor (1) or pressure sensor (9) for use in a motor vehicle, has a coating (5) which has structures with dimensions in the nanometer range, ie. H. in the range 1-100 nm, to make soot deposits or deposits of other foreign bodies more difficult. The structures with dimensions in the nanometer range are preferably formed in a catalytically active material, so that the increased exchange area of these structures increases the catalytic effectiveness and soot that occurs cannot deposit on the sensor, but is completely catalytically decomposed. |
