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.
