Abstract: A haptic device with coupled resonance at tunable frequencies includes an actuator, a first structure coupled to the actuator, a second structure coupled to the first structure and separate from the actuator, and at least one local mass coupled to the first or second structure; the first and second structure having resonance such that application by the actuator of a resonance frequency to the first structure causes the first and second structures to resonate in phase and displace the local mass. A method of forming a haptic device includes coupling an actuator to a first structure, coupling the first structure to a second structure, locating a mass on at least one of the first or second structures, and configuring the actuator to, upon activation, excite the first structure at a resonance frequency of the haptic device such that the first and second structures resonate in phase and displace the mass.

Abstract: 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.

Abstract: Disclosed apparatus may include a membrane, a first electrode supported by the membrane, a second electrode, and optionally a controller configured to control an electrical potential applied between the first electrode and the second electrode. Example apparatus 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. A flexible membrane may include a functionalized polymer or inorganic dielectric material, such as a fluoropolymer composite including at least one electrically conductive additive and/or at least one toughener. Examples also include associated materials (e.g., polymers), methods of fabrication, methods of apparatus operation, and systems.

Abstract: A device configured to provide haptic feedback is disclosed. In one embodiment, at least two actuators, at distinct spatial locations, are coupled to a wearable structure configured to be worn on a portion of a user's body. The device is configured to, in response to receiving an indication from a communicatively coupled device, simultaneously actuate the at least two actuators using a first predetermined haptic signal, such that respective haptic responses generated by the at least two actuators are superimposed to generate a combined haptic response having a magnitude greater than the respective haptic responses generated by the at least two actuators.
