Abstract: A haptic-enabled display device is presented. The haptic-enabled device has a display layer, a first electrode layer, an actuation layer, and an electrode patch. The first electrode layer is disposed on the display layer. The actuation layer is formed of a single piece of actuatable material. A first side of the actuation layer is disposed on the first electrode layer. The single piece of actuatable material of the actuation layer and the conductive material of the first electrode layer may have substantially the same area. The electrode patch may form a second electrode layer, and may be disposed on a second and opposite side of the actuation layer. The electrode patch is electrically connected to a region of the actuatable material, and has an area that is smaller than that of the single piece of actuatable material and smaller than that of the conductive material of the first electrode layer.

Abstract: 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.

Abstract: A touch input system comprising a touch input device and an actuation and sensing system is presented. The actuation and sensing system has a transfer structure adjacent to a first surface of the touch input device, the transfer structure having a first portion and a beam extending from an edge of the first portion. The actuation and sensing system further has a transducer patch disposed on the beam. The transfer structure is configured to transfer forces between the touch input device and the transducer patch, such that movement of the touch input device by an external force causes deformation of the beam and of the transducer patch, and such that actuation output by the transducer patch causes movement of the touch input device. The transducer patch has a layer of transducer material that is configured to act as a sensor, and is configured to act as an actuator.

Abstract: Devices and methods for providing localized haptic effects are provided. The devices include a haptically enabled display device having one or more haptic actuators. The one or more haptic actuators are located in a non-viewing area of a display screen of a haptically enabled display device and cause localized haptic effects in a viewing area of the display screen. The haptically enabled display device includes a processor configured to determine haptic control signals for activating the haptic actuators. The haptic control signal activates the one or more haptic actuators to provide a localized haptic effect at a target location in the viewing area, remote from the non-viewing area location of the one or more haptic actuators.
