Abstract: A variable-stiffness actuator includes a shape-memory member that increases in stiffness on heating, a heating member arranged to surround the shape-memory member along a longitudinal axis of the shape-memory member, and a heat transmitting medium arranged to surround the heating member along a longitudinal axis of the heating member. The heating member generates heat in response to supply of a current, so as to heat the shape-memory member. The heat transmitting medium is deformed to decrease an inner diameter of the heat transmitting medium to come into contact with the heating member, so as to cool the heating member. The heat transmitting medium is deformed to increase the inner diameter to come out of contact with the heating member.

Abstract: An inertial drive actuator includes a displacement unit which generates a minute displacement in a first direction, and in a second direction, a coil which generates a magnetic flux, a movable object which has a surface facing at least one surface of the coil, and a first yoke which converges the magnetic flux generated by the coil, at a predetermined position, a detecting unit which detects an electric signal of the coil, reflecting a change in the magnetic flux near the coil based on a positional relationship of the movable object and the coil, and a judging unit which judges a position of the movable object, and the inertial drive actuator drives the movable object by controlling a frictional force acting on the movable object, by controlling the magnetic flux generated by the coil, and the coil carries out generation of the magnetic flux and detection of the magnetic flux.
