Abstract
An exemplary actuator based on CNT yarns includes a base and a composite film mounted on a surface of the base. The composite film is extendable in a predetermined direction substantially perpendicular to the surface of the base in response to light irradiation applied thereupon. The composite film includes a polymer layer, a plurality of semiconducting CNT yarns dispersed in the polymer layer, and a plurality of metallic CNT yarns dispersed in the polymer layer. A longitudinal of each semiconducting CNT yarn is substantially parallel with the direction. Each semiconducting CNT yarn includes a plurality of twisted semiconducting CNTs. A longitudinal of each metallic CNT yarn is substantially parallel with the direction. Each metallic CNT yarn includes a plurality of twisted metallic CNTs.
