    摘要: Described herein is an electrostatic slide clutch comprising a first electrode, a second electrode oriented parallel to first electrode, an electrically insulating structure disposed on the first electrode on a face of the first electrode opposing the second electrode, and a controller electrically coupled to the first electrode and to the second electrode and configured to apply a variable voltage between the first and second electrodes, to influence a normal force between the first and second electrodes.

    摘要: An electronic device comprises a haptic feedback system. The haptic feedback system includes a first haptic actuator coupled to a controller via a first set of two or more electrodes, and a second haptic actuator coupled to the first haptic actuator, and further coupled to the controller via a second set of two or more electrodes. The controller is configured to provide a first drive signal to the first haptic actuator via the first set of two or more electrodes, and to provide a second drive signal, different from the first drive signal, to the second haptic actuator via the second set of two or more electrodes. Combining two haptic actuators allows for a broader range of feedback and a heightened user experience.

    摘要: One example provides a wireless wearable device including a flexible wearable base configured to be worn at a location of a skeletal joint, an electrostatic clutch including a first electrode, the first electrode having two or more first electrode sheets, each first electrode sheet having a core, a conductive layer formed on the core, and a dielectric coating formed on the conductive layer, and also having a common conductor to which each of the first electrode sheets are connected, and a second electrode having two or more second electrode sheets arranged alternately with the first electrode sheets in a stacked arrangement, a tensioner coupled to the electrostatic clutch, a battery, and control circuitry coupled to the electrostatic clutch and configured to generate a control signal to control an electrostatic force between the two or more first electrode sheets and the two or more second electrode sheets.

    摘要: An electrostatic slide clutch comprises first and second sheet electrodes, a dielectric layer, and a drive circuit. The dielectric layer is arranged between the first and second sheet electrodes. The drive circuit is coupled electrically to the first sheet electrode and to the second sheet electrode and configured to move a variable amount of charge bidirectionally between the first and second sheet electrodes, to influence a normal force between the first and second sheet electrodes.
