Abstract: An engine system is provided. The engine system includes a passageway having an inner surface and an outer surface. The passageway is adapted to allow a flow of air therethrough. The engine system also includes a sensor provided in the passageway and in contact with the air. The sensor is adapted to sense a parameter of the air. The engine system further includes a hydrophobic coating having a micropatterned texture provided on at least one of the inner surface of the passageway and the sensor. The hydrophobic coating is adapted to limit deposition of at least one of a fluid and a solid thereon.
