An active fluid transport device (10, 40, 54, 60) that includes a layer (12) of polymeric material. The layer (12) has a structured surface (13) that includes a plurality of substantially discrete flow channels (16). The flow channels (16) have a minimum aspect ratio of about 10 to 1 and a hydraulic radius no greater than about 300 micrometers. The device may also include a connector (20, 55) that allows a potential source (14) external to the structured surface (13) to be placed in fluid communication with the discrete flow channels (16). The potential source (14) promotes fluid movement through the flow channels (16) from a first location to a second location.

[ What is claimed is:] [1.]1. An active fluid transport device that comprises:(a) a layer of polymeric film material having a first major surface that includes a structured surface that has a plurality of discrete flow channels disposed thereon, the flow channels extend from a first point to a second point along the structured surface and have a minimum aspect ratio of about 10:1 and a hydraulic radius no greater than about 300 micrometers;(b) a source external to the structured surface for providing a potential over the flow channels; and(c) a connector that is in fluid communication between the discrete flow channels and the external source, which connector allows the potential from the source external to the structured surface to be applied to the flow channels to promote fluid movement through the flow channels from a first location to a second location.
