摘要： 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.

摘要： 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.

摘要： A haptic-enabled user interface device comprising a user input component, an elastomer suspension, a signal generating circuit, a signal sensing circuit, one or more switches, and a control unit is presented. The elastomer suspension is formed by at least one stack that includes an elastomeric layer, wherein the at least one stack forms at least one capacitor. The control unit is configured, in an actuation mode, to cause the one or more switches to electrically connect the signal generating circuit to the at least one capacitor and to electrically disconnect the signal sensing circuit from at least one capacitor, and to cause the signal generating circuit to apply a drive signal to the at least one capacitor. The control unit is further configured, in a sensing mode, to cause the one or more switches to electrically connect the signal sensing circuit to the at least one capacitor.

摘要： One illustrative system disclosed herein includes an enclosure configured to define a boundary of a chamber, the chamber including a material, and a flexible layer coupled overtop of the chamber and configured to enclose the chamber. The illustrative system also includes a first actuation device configured to receive a first haptic signal and responsively output a first haptic effect by changing a characteristic of the material to deform the flexible layer. The illustrative system also includes a second actuation device configured to receive a second haptic signal and responsively output a second haptic effect by applying an electrical signal to the flexible layer. The illustrative system further includes a processor in communication with the first actuation device and the second actuation device. The processor is configured to transmit the first haptic signal to the first actuation device and the second haptic signal to the second actuation device.

摘要： A haptic system includes a structure having a conductive layer and a reactive layer. The conductive layer is coupled to a power source and the reactive layer is coupled to a switch having a first state and a second state. The power source enables the conductive layer to generate a charge. The first state of the switch operates the reactive layer to block the establishment of a tissue-stimulating electric field. The second state of the switch operates the reactive layer to enable the establishment of a tissue-stimulating electric field to generate a touchless haptic effect.

摘要： A haptic effect enabled system generates a haptic effect using an electric potential responsive fluid. A haptic enabled apparatus includes a fluid and a substrate. The fluid is responsive to an electric field. The substrate is at least partially flexible and defines a channel. The fluid is positioned within at least a portion of the channel. A portion of the substrate proximal to the fluid is stiffer than a portion of the substrate spaced from the fluid, thereby creating a haptic effect.
