Abstract

Apparatus for inducing, impeding, selectively filtering or otherwise effecting fluid flow in microfluidics applications. Opposing mesh layers are placed into relative motion by a variety of motive forces. Fluid between the opposing mesh layers is compressed so as to be pumped through the mesh layers when the relative motion of the layers is toward each other. Mesh layers may also be offset from each other though an actuating force so that one mesh layer blocks the openings in the other mesh layer, thereby creating an impediment to fluid flow. The degree of offset may be varied so as to create a partial impediment to fluid flow, thereby presenting a filter effect.
