    Abstract: 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.

    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: An electret-based haptic actuator is presented. The actuator having an electret layer, an electrically conductive layer, an electrically insulative layer, a plurality of spacers, and a signal generating circuit. The electret layer having a built-in voltage along a thickness dimension of the electret layer. The electrically insulative layer being disposed between the electret layer and the electrically conductive layer. The plurality of spacers being disposed between the electret layer and the electrically conductive layer. The signal generating circuit being electrically connected to the electrically conductive layer and not electrically connected to the electret layer. The signal generating circuit being configured to apply an oscillating drive signal to the electrically conductive layer to generate a vibrotactile haptic effect.

    Abstract: The present application relates generally to haptic feedback actuators and their construction and use in touch based systems. The haptic feedback actuators are suitably bilayer structures including at least two materials having different thermal coefficients, allowing the structure to deflect from a first position to a second position in response to heating and/or cooling of the structure.
