Abstract
A channel-less microfluidic pump includes a cartridge including a substrate and an actuatable film layer disposed on the substrate, and a manifold having at least three actuatable void volumes separated by a plurality of wall sections and an actuatable flexible layer disposed on the manifold interfacing the actuatable film layer. In operation, the pump can be in an unactuated state wherein the actuatable film layer is disposed against the surface of the substrate or an actuated state wherein at least a portion of the flexible layer and a corresponding portion of the actuatable film layer are deflected into a corresponding void volume thus forming a fluidic volume between the deflected portion of the actuatable film layer and the surface of the substrate. In the actuated state, there is a fluidic gap between immediately adjacent void volumes formed by a thinned region of the flexible layer at a point of contact with a top surface of a wall section. A method of transporting fluid using the channel-less microfluidic pump is described.
