Abstract: A 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 5 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.

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.

Abstract: An optically transparent 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.

Abstract: An optically transparent force sensor, which may be used as input to an electronic device. The optically transparent force sensor may be configured to compensate for variations in temperature using two or more force-sensitive components that are formed from materials having different temperature- and strain-dependent responses. 013361\191 1\11707067.1
