Soft robotics is an expanding and promising field that deeply transforms the way we design actuators and sensors. Despite recent progress, there is still a need for electrically driven actuators being capable of providing large motions under low voltage. We explore here the concept of phase transition-driven actuators, in which the actuation only results from the large expansion taking place during a liquid to a gas phase transition. We demonstrate that such a concept can be used for creating original applications, including a morphable skin with controllable texture and a soft gripper. It would be very challenging, if not impossible, to design such actuators with other actuation technologies while preserving the same compactness.
