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.

Fluidic devices and related methods and wearable devices

Co-casted fluidic devices

A fluidic-device valve may include a valve guide having a guide wall surrounding a central axis. The guide wall may include a first guide section, a second guide section, and an interior surface that defines a valve cavity extending longitudinally along the central axis from the first guide section to the second guide section. The valve may also include a valve member having a ferromagnetic material disposed within the valve cavity, and the valve member may extend longitudinally along the central axis. The valve member may also have a first plug section and a second plug section and may define a fluid conduit between the first plug section and the second plug section. Various other methods, systems, and computer-readable media are also disclosed.

Electromagnetically actuated fluidic-device valve apparatuses, systems, and methods

The disclosed fluidic device may include (1) a channel configured to transport fluid from a source to a drain and (2) a gate configured to modulate fluid flow through the channel. The gate may modulate fluid flow by bending a gate actuation membrane that alternates between an initial configuration that does not interfere with a cross section of the channel and a bent configuration that causes the cross section to reversibly compress. The gate actuation membrane may include an undulation that facilitates the bending of the gate actuation membrane.

Apparatuses, systems, and methods for modulating fluid flow within a fluidic device

Systems and methods for forming a fluidic device using a layered construction strategy may include (1) forming a first component for the fluidic device out of a first material, (2) forming a second component for the fluidic device out of a second material that is different than the first material, and (3) after forming the first and second components, forming the fluidic device by assembling a variety of components including the first component and the second component.

Apparatuses, systems, and methods for a layered construction of fluidic devices

A haptic device provides haptic sensation to a user. The haptic device comprises a haptic plate and a plurality of actuators. The haptic plate includes a center portion and an outer portion that circumscribes the center portion. The plurality of actuators is coupled to the outer portion of the haptic plate. Of the plurality of actuators, one or more actuators are configured to generate, in accordance with haptic instructions, a haptic wave that converges to a specific waveform at a specific region of the center portion of the haptic plate. The shape of the specific waveform and the location of the specific region on the center portion of the haptic plate are based in part on the haptic instructions.
