Abstract

Example embodiments relate to microfluidic devices for controlling pneumatic microvalves. One embodiment includes a microfluidic device for independently controlling a plurality of pneumatic microvalves. The microfluidic device is couplable to a pressure source. The microfluidic device includes a first substrate. The microfluidic device also includes a flexible membrane covering the first substrate. Additionally, the microfluidic device includes a second substrate covering the flexible membrane. Further, the microfluidic device includes one or more fluidic channels at least partially defined in the first substrate. In addition, the microfluidic device includes a pressure couplable to the pressure source and branching into a plurality of pressure channels. Still further, the microfluidic device includes at least one pressure control switch per pressure channel.
