  • Patent number: 10584689
    Abstract: A haptic actuator device includes a surface with a mechanical property responsive to localized temperature changes. The surface can include a layer or sheet comprising a shape-memory material. The haptic actuator device can further include an actuator configured to selectively deform a plurality of regions in the sheet; and a temperature controller adapted to control the temperatures of the plurality of regions. A method of localized actuation includes selectively controlling the temperatures of the plurality of regions to be above a shape-memory transition temperature of the shape-memory material; selectively deforming at least one of the regions; while maintaining the deformation of the at least one region, lowering the temperature of the at least one region to below the shape-memory transition temperature; subsequently withdrawing the applied stress; and thereafter heating the at least one region to above the shape-memory transition temperature, causing the region to return to its pre-deformation shape.

  • Patent number: 10583359
    Abstract: A wearable device for providing haptic effects includes a wearable housing configured to be worn on to a portion of a hand of a wearer and an actuator secured to the wearable housing. The wearable housing includes a first digit segment configured to conform to a finger of the hand and a second digit segment configured to conform to another finger or a thumb of the hand. The actuator is configured to receive a command signal indicative of a virtual interaction related to touching or grasping a virtual object. In response to the command signal, the actuator provides a force onto the portion of the hand or provides a force to render a resistance to movement of the first and second digit segments toward each other. The actuator uses the wearable housing to mechanically stabilize the force towards the portion of the hand.

    Abstract: A haptic actuator assembly includes a haptic actuator configured to output displacement along a perpendicular axis and a pre-load device. The pre-load device is disposed adjacent to the haptic actuator and configured to generate a compressive load on the haptic actuator along the perpendicular axis to oppose expansion of the haptic actuator along the perpendicular axis. The haptic actuator is disposed within an enclosed cavity formed by a casing. A pressure within the enclosed cavity is varied in order to create the compressive load on the haptic actuator along the perpendicular axis. The pre-load device may alternatively be a connector component formed from a shrinkable material that is configured to longitudinally shrink to exert a force in order to create the compressive load on the haptic actuator along the perpendicular axis.
