The disclosed fluidic devices may include a valve chamber in a valve body, a fluid inlet into the valve chamber, a piston positioned within the valve chamber, a first fluid outlet for passing fluid out of the valve chamber when the piston is in a first position, a second fluid outlet for passing fluid out of the valve chamber when the piston is in a second position, a first piezoelectric actuator positioned and configured for moving the piston from the first position to the second position, and a second piezoelectric actuator positioned and configured for moving the piston from the second position to the first position. Various other methods, systems, and devices are also disclosed.

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.
