Abstract
A sensing element includes a substrate including an electrically non-conductive surface, at least one high surface energy region, and an electrode pair structure disposed on the electrically non-conductive surface. The electrode pair structure includes at least one pair of electrodes having a gap therebetween. At least one of the electrodes is at least partially within the at least one high surface energy region. The sensing element is configured to sense fluid-soluble particulate matter.
