  • Co-casted fluidic devices
    Patent number: 11204100
    Abstract: A fluidic device comprises a channel, a gate, and one or more additional elements. The channel is configured to transport a fluid from a source to a drain. The gate includes a chamber with an adjustable volume that affects fluid flow within the channel by displacing a wall of the channel toward an opposite wall of the channel based in part on fluid pressure within the chamber exceeding a threshold pressure. A high pressure state of the gate corresponds to a first chamber size and a first flow rate of the fluid. A low pressure state of the gate corresponds to a second chamber size that is smaller than the first chamber size and a second flow rate that is greater than the first flow rate. The additional elements are configured to reduce the threshold pressure past which the chamber decreases the cross-sectional area of the channel.
