Abstract
A sensor includes an electrode and a seed structure. The electrode is configured to measure current due to movement of particulate matter relative to the electrode. The seed structure is deposited on the electrode. The seed structure includes a plurality of elongated members extending outward from the surface of the electrode. The elongated members are configured to promote charge transfer to particles and/or agglomerates of the particulate matter during operation of the sensor.
