EPITAXIAL SOOT SENSOR

A soot sensor has a soot-sensitive noble-metal structure formed as strip conductor sections on an electrically insulating carrier, whose strip conductor sections are between 5 and 100 μm wide and are spaced apart from each other between 5 and 100 μm. The electrically insulating carrier may be a sing...

Zusammenfassung:A soot sensor has a soot-sensitive noble-metal structure formed as strip conductor sections on an electrically insulating carrier, whose strip conductor sections are between 5 and 100 μm wide and are spaced apart from each other between 5 and 100 μm. The electrically insulating carrier may be a single crystal and the noble metal crystallized out on a surface of the single crystal, or the electrically insulating carrier may be polycrystalline and the noble metal crystallized out on the polycrystalline, electrically insulating carrier.
