Abstract
A particulate matter sensor system for sensing particulate matter in a fluid includes a substrate and a cover disposed on the substrate. The cover defines at least a portion of a flow path through the microfluidic system. The sensor system includes a particulate matter sensor disposed in an interior space between the cover and the substrate. The particulate matter sensor includes an integrated sensor device electrically connected to the substrate. The flow path is defined through the particulate matter sensor. The sensor system includes a fluid circulation device disposed in the interior space between the cover and the substrate and configured to cause fluid to flow along the flow path through the microfluidic system.
