SOOT SENSING SYSTEMS HAVING SOOT SENSORS AND METHODS FOR MANUFACTURING THE SOOT SENSORS

摘要

Soot sensing systems and soot sensors are provided. In one exemplary embodiment, a soot sensor includes a non-conductive substrate and a first electrode disposed on the non-conductive substrate. The soot sensor further includes a second electrode disposed on the non-conductive substrate and spaced away from the first electrode. The soot sensor further includes a first protective layer disposed over at least a portion of the first electrode. The soot sensor further includes a second protective layer disposed over at least a portion of the second electrode. Further, an electrical parameter between the first and second electrodes is indicative of an amount of soot disposed on the non-conductive substrate between the first and second electrodes.
