Abstract
Microfluidic flow control devices are provided. In one embodiment, a regulating device includes overlapping channel segments separated by a deformable membrane in fluid communication with one another. Pressure differentials between the channel segments deform the membrane towards the channel with the lower pressure, thereby restricting flow. The restricted flow increases pressure in the low pressure channel, reversing the deformation of the membrane and regulating the pressure between the channels
