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.
