Abstract
A microfluidic device includes an input source characterized by a source pressure, an input channel in fluid communication with the input source, and an output channel. The microfluidic device also includes a normally closed valve having a closed state and an open state. The normally closed valve is disposed between the input channel and the output channel. The microfluidic device further includes one or more release chambers coupled to a pressure source. Activation of the pressure source deforms the one or more release chambers, placing the normally closed valve in the open state.
