Abstract
One or more buttons on an electronic device are mechanically coupled to actuators utilizing electroactive polymers. When active, the electroactive polymer deploys the button such that a height of the button above a substrate is increased. When inactive, the button returns to a stowed position having a lower height, and thus presents a lesser profile.
