Abstract
A flow controller can include a conduit wall and a membrane coupled to the conduit wall. The membrane is configured to obstruct gas flow through the conduit. The flow controller includes a membrane controller, positioned adjacent to the membrane, wherein the membrane is positioned on one side of the membrane controller, such that the membrane controller impedes bending of the membrane in a second direction different from the first direction, thereby restricting gas flow through the conduit.
