    Abstract: In some embodiments, a haptic actuator includes piezoelectric material and a pattern of voltage electrodes coupled to a surface of the piezoelectric material. The voltage electrodes are individually controllable to supply voltage to different portions of the piezoelectric material. Different sections of the piezoelectric material are operable to deflect, producing haptic output at those locations, in response to the application of the voltage. Differing voltages may be provided to one or more of the voltage electrodes to affect the location of the deflection, and thus the haptic output. In various embodiments, a haptic output system incorporates a sealed haptic element. The sealed haptic element includes a piezoelectric component that is coupled to one or more flexes and is sealed and/or enclosed by the flex(es) and an encapsulation or sealing material.

    IPC: G01L1/22

    Abstract: One or more strain sensors can be included in an electronic device. Each strain sensor includes a strain sensitive element and one or more strain signal lines connected directly to the strain sensitive element. The strain sensor(s) are 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 or surface of the electronic device. A strain sensitive element is formed or processed to have a first gauge factor and the strain signal line(s) is formed or processed to have a different second gauge factor. Additionally or alternatively, a strain sensitive element is formed or processed to have a first conductance and the strain signal line(s) is formed or processed to have a different second conductance.
