Abstract: A passive microvalve comprises a substrate having a first aperture. An upper plate is mounted on the substrate and has a second aperture opening into a space defined between the substrate and the upper plate. A closure member is mounted in the space and is movable between a first position in which it allows fluid flow between the first and second apertures and a second position in which it closes the second aperture.
