In microfluidics, a purge valve is relieves the gas in a microchannel for a gas-liquid phase fluid. There is a demand for a purge valve that can alter the flow of fluids automatically without sensing feedback. However, existing valve designs with this feature are complicated in their operation and very costly to fabricate.

Purdue University researchers have developed a novel purge valve that can be used for fluid alignment in a microfluidic chip. This valve can automatically align fluids without sensing feedback, giving it an advantage over valves currently on the market. It is less expensive to manufacture and simpler to operate than competing designs that also do not require feedback sensing.

Advantages:
-Integrates with existing microfluidic chips
-Low cost of fabrications
-Does not require feedback sensing
-Simple operation

Potential Applications:
-Purge valve
-Microfluidic chips
