Abstract:
1. A microfabricated fluidic unidirectional valve comprising: a first layer of microfabricated elastomer material, a second layer of microfabricated elastomer material, and a flow through channel disposed between the first layer of microfabricated elastomer material and the second layer of microfabricated elastomer material; and an elastomer flap attached to the first layer of microfabricated elastomer material, wherein the elastomer flap extends substantially normally to the first layer of microfabricated elastomer material; wherein the elastomer flap forms a seal in the flow through channel to prevent fluid from flowing in a first direction through the flow through channel, and to allow fluid to flow in a second direction through the flow through channel.
