Abstract

In one embodiment, a peristaltic micropump comprising a substrate having a first side and a second side, a microtube that extends across the first side of the substrate, and multiple pump actuators formed on the first side of the substrate and positioned adjacent to the microtube at discrete, spaced positions along the length of the microtube, wherein the micropump is configured to sequentially actuate the pump actuators so as to create peristaltic action that drives fluid contained in the microtube along the length of the tube.
