    Abstract: A bi-functional apparatus for sensing touch and delivering a haptic signal. The bi-functional apparatus comprises first and second electrodes. The first electrode provides a haptic interface for delivering an electrostatic force and has a top surface and a bottom surface. A dielectric insulator covers the top surface of the first electrode. A sensor is positioned between the bottom surface of the first electrode and the second electrode. The sensor selectively provides electrical conductivity between the first and second electrodes in response to at least a threshold amount of pressure exerted against the dielectric insulator. A method of sensing touch and delivering a haptic signal with a single device. The method comprises receiving an input at a touch surface of a dielectric insulator layered over a first electrode; in response to receiving the input at the touch surface, increasing the electrical conductivity of a sensor positioned between the first electrode and a second electrode; in response to increasing electrical conductivity of the sensor, conducting an electrical current between the first and second electrodes; and in response to conducting an electrical current between the first and second electrodes, applying a haptic drive signal to the first electrode, the haptic drive signal creating an electrostatic force in the dielectric insulator.

    Abstract: A haptic actuator comprising a first actuation component and a second actuation component is presented. The first actuation component comprises a first layer of actuatable material and electrodes on opposite sides of the first layer, wherein the actuatable material is configured to deform upon any electrical signal being applied to at least one of the electrodes. The haptic actuator further comprises a second layer separated from the first actuation component by one or more spacers. The second actuation component comprises a magnetized material and one or more electromagnets. Either the magnetized material or the one or more electromagnets are disposed on the first actuation component, and relative movement between the magnetized material and the one or more electromagnets is generated upon any electrical signal being applied to the one or more electromagnets, wherein the relative movement causes vibration of the first actuation component.

    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 pre-load device includes a casing and at least a first spring component. The casing includes a cover and a base spaced apart from and extending parallel to the cover. The haptic actuator is disposed between the cover and the base, and the first spring component is configured to exert a force in order to create the compressive load on the haptic actuator along the perpendicular axis.

    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. The wearable device may further include a sensor configured to sense a dynamic response to a user interaction with a real-world object which corresponds to the virtual object, the sensed dynamic response being used to assess a physical characteristic of the real-world object.
