Switchable fluidic device

A fluidic device comprising:

• a channel conduit including a fluid entrance to the channel conduit and a fluid exit from the channel conduit, the channel conduit bounded by an inner surface that includes a protrusion that protrudes into the channel conduit;
• a flexible element inside the channel conduit, the flexible element having at least one edge coupled to the inner surface of the channel conduit on a different side of the inner surface as the protrusion, the flexible element having an adjustable position;
• a cross member with a first end and a second end, the first end coupled to a deformable surface and the deformable surface is part of the inner surface of the channel conduit and the second end is coupled to the flexible element;
• and
• a gate configured to impart an amount of deformation to the deformable surface in accordance with an applied fluid pressure at the gate, and the amount of deformation controls the adjustable position of the flexible element via the cross member.
