Abstract
A fluidic device controls fluid flow in channel from a source to a drain. In some embodiments, the fluidic device comprises a channel and a gate. The channel is configured to transport a fluid from the source to the drain. The gate controls a rate of fluid flow in the channel in accordance with the fluid pressure within the gate. Specifically, the gate is configured to induce a first flow rate of the fluid in the channel in accordance with a low pressure state of the gate, and a second flow rate of the fluid in the channel in accordance with a high pressure state of the gate. In certain embodiments, the first flow rate is greater than the second flow rate. In alternative embodiments, the second flow rate is greater than the first flow rate.
