Abstract: Electromechanical actuators may be constructed as cylindrical elements with electrodes position around the cylindrical element. The electrodes may receive an electrical signal that causes a core material in the electromechanical actuator to change shape, thus providing haptic feedback to a user, such as when the actuators are integrated with a display screen of a smart phone. A position of the electrodes around the core material may affect a mode of operation of the electromechanical actuators. In one configuration, two electrodes may be located at opposite ends of the cylindrical element along a long axis of the cylinder. In another configuration, two electrodes may be located opposite each other along a circumference of the cylinder. Signals may be applied to the electrodes to generate vibrational feedback or textures on the display screen.

Abstract: User feedback may be generated and user input received through a single semiconductor component integrated into the electronic device. The single semiconductor component may include a piezoelectric cantilever actuator integrated with a transistor, such as a thin-film transistor, such that the actuator is electrically isolated from the transistor but mechanically attached to the transistor. One manner of integration is to extend a piezoelectric thin film of the actuator into a gate electrode stack of the transistor. The cantilever actuator may be controlled to provide haptic feedback. Separate from, and possibly simultaneously with the control of the cantilever actuator, user input may be received through the transistor integrated with the cantilever actuator.
