摘要： Haptic actuators may include a first active material coupled to a first side of an inactive substrate and a second active material coupled to a second side of the inactive substrate. The inactive substrate may be formed to initially exhibit a nonplanar shape when the first active material and the second active material are not actuated. Various other methods, systems, and devices are also disclosed.

摘要： The disclosed haptic feedback system may include an actuator, a supply valve coupled to the actuator, an exhaust valve, and a fluidic mass controller communicatively coupled to the supply valve and the exhaust valve. The fluidic mass controller may (1) place the exhaust valve in a state that prevents a fluid from escaping the actuator, (2) activate the supply valve to fill the actuator with an amount of the fluid, (3) determine that the actuator has filled with the amount of the fluid, and then in response to that determination, (4) deactivate the supply valve to trap the amount of the fluid in the actuator. Various other apparatuses, methods, and systems are also disclosed.

摘要： The disclosed haptic vibrotactile actuators on inflatable bladders may include an inflatable bladder and a flexible haptic vibrotactile actuator positioned on or in the inflatable bladder such that inflation and deflation of the inflatable bladder alters a vibrotactile sensation induced by the flexible haptic vibrotactile actuator in response to activation of the flexible haptic vibrotactile actuator. Various other related methods and systems are also disclosed.

摘要： 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.

摘要： Systems and methods of controlling activation of different input elements using an actuator are disclosed herein. An example method includes in response to detecting that a representation of a finger is located by a first input element: obtaining information regarding a first amount of force to actuate the first input element, and causing adjustment of a physical characteristic of an actuator so that a first amount of force directed to a component of the actuator activates the first input element. In response to detecting that the representation of the finger is located by a second input element, the method also includes: obtaining information regarding a second amount of force distinct from the first amount of force, and causing adjustment of the physical characteristic of the actuator so that the second amount of force directed to the component of the actuator activates the second input element.

摘要： A method of adjusting a neuromuscular-signal sensor is provided. The method includes monitoring, based on data from a wearable device that includes a neuromuscular-signal sensor, an impedance at the sensor that impacts the neuromuscular-signal sensor’s ability to sense neuromuscular signals. The neuromuscular-signal sensor is coupled to the wearable device such that it contacts a portion of a user’s skin. In response to detecting a change in the impedance at the neuromuscular-signal sensor that causes the impedance to be outside of a predefined range of impedance values, the method includes causing an adjustment to an operational characteristic (e.g., causing the neuromuscular-signal sensor to move or adjusting an electrical characteristic) associated with the neuromuscular-signal sensor such that the impedance at the neuromuscular-signal sensor is within the predefined range of impedance values after the adjustment to the operational characteristic.

摘要： An optical transformer includes a light source and an array of photovoltaic cells optically coupled to the light source, where at least a portion of the photovoltaic cells are connected in series. An optical connector such as a waveguide or an optical fiber may be disposed between an output of the light source and an input of the array of photovoltaic cells. Configured to generate a high voltage output, the optical transformer may be configured to power a device such as an actuator that provides a tunable displacement as a function of voltage.
