Abstract
The disclosed microfluidic valves may include a valve body having at least one cavity therein, a gate transmission element separating the cavity into an input gate terminal and an output gate terminal, a gate port configured to convey drive fluid into the input gate terminal, and a fluid channel. The gate transmission element may include a flexible membrane and a plunger coupled to the flexible membrane. The gate transmission element may be configured to move within the cavity to inhibit a subject fluid flow from an inlet port to an outlet port of the fluid channel upon pressurization of the input gate terminal, and to allow subject fluid flow from the inlet port to the outlet port upon depressurization of the input gate terminal. Various other related systems and methods are also disclosed.
