Abstract
An actuator according to one aspect of the present invention includes a first member in which a shape is transformed from a first position, which is either rolled or flat, to a second position different from the first position, and a restoring force is stored when the shape is transformed from the first position to the second position, and a second member which is joined to the first member along the length direction of the first member and in which the shape of the second position is stored.
Claims16
A self-transformable actuator comprising:
- a first member having a shape which is transformable from a first position to a second position different from the first position, the first member being configured to store restoration force based on the shape being transformed from the first position to the second position, wherein the first position is in one of a rolled state or an unrolled state;
- and
- a second member bonded to the first member in a longitudinal direction of the first member, and configured to store the shape of the second position,
- wherein the first member is configured to maintain the first position when no heat is applied to the second member, transform the shape from the first position to the second position when heat is applied to the second member, and store the restoration force to restore to the first position when the shape is transformed to the second position, and
- wherein the second member is configured to transform from the first position to the second position when heat is applied to the second member, and change shape from the second position to the first position when the restoration force is applied to the second member by the first member.
