Abstract

A particulate matter sensor includes a first sensing electrode and a second sensing electrode spaced away from the first sensing electrode such that an electrode gap is formed between the first sensing electrode and the second sensing electrode upon which particulate matter is collected, thereby changing conductance between the first sensing electrode and the second sensing electrode. An ionic conductive material is in electrical communication with the first sensing electrode and the second sensing electrode.
