Abstract
The present disclosure provides for an apparatus for transferring fluid. The apparatus has a fluid transfer component, a fluid receiving component, a fluid supply, and a fluid motivating component. The fluid transfer component has a first surface, a second surface, a non-random pattern of distinct pores each defining a pathway between the first and second surfaces, a single entry point at the first surface, and a single exit point at the second surface. The pores are disposed at preselected locations to provide a desired pattern of permeability. The fluid receiving component comprises a fluid receiving surface. The fluid supply is adapted to provide a fluid in contact with and at a constant fluid pressure with the first surface of the fluid transfer component. The fluid motivating component is adapted to facilitate transport of the fluid from the first surface through the pores to the second surface.
