Abstract
A fluidic device controls fluid flow in channel from a source to a drain. The fluidic device may be combined with other fluidic devices to form different types of logic devices g an inverter, OR gate, etc.). And the logic devices may be incorporated into an artificial reality system (e.g., as part of a haptic assembly). In some embodiments, a fluidic device includes a gate, a channel, and a wedge. The wedge controls a rate of fluid flow within the channel based on a fluid pressure in the gate. The wedge induces a first flow rate of 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, the second flow rate greater than the first flow rate.
