An exemplary device and method for microfluidic transport is disclosed as providing inter alia a valve membrane sheet (400), an inlet channel (140) and an outlet channel (150). The valve membrane sheet effectively confines transport of fluid from the inlet channel to the outlet channel where fluid may be purged. The valve membrane sheet also generally provides means for preventing or otherwise substantially decreasing the incidence of purged fluid re-entering the inlet channel. Accordingly, the reduction of backflow generally tends to enhance overall pumping performance and efficiency. Disclosed features and specifications may be variously controlled, adapted or otherwise optionally modified to improve micropump operation in any microfluidic application. Exemplary embodiments of the present invention representatively provide for substantially self-priming micropumps that may be readily integrated with, for example, existing portable LTCC technologies for the improvement of device package form factors, weights and other manufacturing and/or device performance metrics.
