Title: ACTUATOR AND METHOD FOR MANUFACTURING SAME
Abstract:
This actuator comprises a fibrous polymer material configured from a polymer and has twist marks in the outermost surface of the fibrous polymer material, wherein an angle x, at which the twist marks are inclined relative to a fiber axis of the fibrous polymer material, and an angle y, at which the twist marks are inclined relative to the fiber axis of the fibers when the fibers configured from the polymer constituting the fibrous polymer material are twisted to the limit at which coiling occurs or to the limit of breaking while under a tensile stress equal to the elastic modulus of the fibers multiplied by 4.5 × 10-3 in an environment at 25°C, satisfy the relationship x > y + 0.5.
