Abstract: An electronic device is configured to provide localized haptic feedback to a user on one or more regions or sections of a surface of the electronic device. The localized haptic feedback is provided by an array of piezoelectric haptic actuators below the surface of the electronic device. Actuators within the array of piezoelectric haptic actuators are separately controllable by a control circuit layer. The control circuit layer includes control circuitry, a master flexible circuit which passes between rows of actuators, and an array of slave flexible circuits. Each slave flexible circuit is connected to the master flexible circuit and an actuator. In further examples, the array of piezoelectric haptic actuators provides a unified structure for detecting touch and force inputs.

Abstract: One or more transparent transistor force sensitive structures can be included in an electronic device. The transistor force sensitive structures(s) is used to detect a force that is applied to the electronic device, to a component in the electronic device, and/or to an input region of the electronic device. As one example, the one or more transparent transistor force sensitive structures may be included in a display stack of a display in an electronic device.

Abstract: An electronic device includes one or more transparent strain sensors configured to detect strain based on an amount of force applied to the electronic device, a component in the electronic device, and/or an input surface of the electronic device. The one or more transparent strain sensors may be included in or positioned below an input surface that is configured to receive touch inputs from a user. The area below the input surface can be visible to a user when the user is viewing the input surface. The one or more transparent strain sensors are formed with a nanostructure, including a nanomesh or nanowires.

Abstract: An electronic device configured to provide localized haptic feedback to a user on one or more regions or sections of a surface of the electronic device. A support structure is positioned below the surface, and one or more haptic actuators are coupled to the support structure. In some examples, the support structure is shaped or configured to amplify a response to a haptic actuator. When a haptic actuator is actuated, the support structure deflects, which causes the surface to bend or deflect at a location that substantially corresponds to the location of the activated haptic actuator. In some examples, prior to providing haptic feedback, at least one haptic actuator is electrically pre-stressed to place the haptic actuator(s) in a pre-stressed state. When haptic feedback is to be provided, at least one haptic actuator transitions from the pre-stressed state to a haptic output state to produce one or more deflections in the surface. In other examples, a haptic structure incorporates a piezoelectric element that is shaped to reduce the overall cost of the haptic structure while still providing high actuation performance.

Abstract: An optical force sensor that may compensate for environmental effects, including, for example, variations in temperature of the device or the surroundings. In some examples, two force-sensitive layers are separated by a compliant layer. The relative electrical response of the two force-sensitive layers may be used to compute an estimate of the force of a touch that reduces the effect of variations in temperature. In some examples, piezoelectric films having anisotropic strain properties are used to reduce the effects of temperature.
