Abstract: Disclosed devices may include a membrane, a first electrode supported by the membrane, a second electrode, a capacitance sensor configured to determine a capacitance measurement between the first electrode and the second electrode, and a controller configured to control an electrical potential applied between the electrode and the second electrode. The controller may be configured to modify the electrical potential based on the capacitance measurement. Example devices may include one or more flexible membranes that may, at least in part, define an enclosure that is at least partially filled with a dielectric fluid. Examples also include associated methods and systems.

Abstract: The disclosed microfluidic valves may include a valve body having at least one cavity therein, a gate transmission element separating the cavity into an input gate terminal and an output gate terminal, a gate port configured to convey drive fluid into the input gate terminal, and a fluid channel. The gate transmission element may include a flexible membrane and a plunger coupled to the flexible membrane. The gate transmission element may be configured to move within the cavity to inhibit a subject fluid flow from an inlet port to an outlet port of the fluid channel upon pressurization of the input gate terminal, and to allow subject fluid flow from the inlet port to the outlet port upon depressurization of the input gate terminal. Various other related systems and methods are also disclosed.

Abstract: A high voltage-driven system includes a high voltage optical transformer and a high voltage driven device, where the high voltage optical transformer is located in close proximity to the high voltage driven device. A high voltage connection between the high voltage optical transformer and the high voltage driven device may be shorter than a low voltage connection between the high voltage optical transformer and a low voltage power source used to control the transformer.

Abstract: The disclosed lockable beams for haptics applications may include a rib structure including a plurality of ribs, a linking structure connecting the ribs to each other, a tendon extending along the rib structure, a tensioner coupled to the tendon for applying tension to the tendon, and a locking mechanism configured to, when engaged, impede relative movement between the tendon and the rib structure in a manner that impedes bending of the lockable beam. Various other methods, systems, and devices are also disclosed.
