Abstract: A method of making an actuator having a complex internal shape includes providing a core of a shape that defines an internal cavity of an actuator; molding an actuator around the core, wherein the core occupies the internal cavity of the actuator, the cavity having an opening; generating a pressure differential between an exterior surface of the actuator and the internal cavity of the actuator, wherein the external pressure is less than the internal pressure, to expand the actuator cavity; and removing the core through the opening of the expanded actuator cavity.
