Abstract:
1. A microfabricated fluidic unidirectional valve comprising: a feed-through port bounded by a first elastomeric layer; a membrane fixed to the first elastomeric layer; a flow channel at least partly bounded by the first elastomeric layer, wherein the membrane selectively forms a seal with the first elastomeric layer to prevent fluid flow from the flow channel to the feed-through port and to allow fluid flow from the feed-through port through the flow channel; a second elastomeric layer bounding the flow channel; and a first spacer fixed to the second elastomeric layer and to the membrane, wherein the membrane is between the first spacer and the first elastomeric layer.
