The present invention relates to a rotation-type actuator comprising a fiber having a twisted structure, which is manufactured by rotating the same in opposite directions, wherein the fiber is divided into a top portion and a bottom portion, with reference to the center, at least one of the top portion and the bottom portion of the fiber is fixed, each of the top portion and the bottom portion of the fiber is characterized by having a coil that is twisted in a chiral Z-type or chiral S-type structure independently, and the actuator not only has an excellent rotating force, when there is a temperature fluctuation, but also exhibits excellent durability and stability such that there is unnoticeable reduction in rotating force even after a long time of use. In addition, the rotation-type actuator according to the present invention is characterized in that a polymer fiber, which has been manufactured by electrospinning, is solely used, or a polymer sheet, which is obtained by aligning the polymer sheet in a single direction, is twisted and coiled to manufacture the same. The actuator uses a persistent temperature gradient, which is supplied from temperature differences existing in ordinary environments, and has actuation that is reversible, fast, and efficient such that heat energy, which is wasted in the air, can be efficiently converted into mechanical energy without providing any artificial temperature change. Therefore, the present invention can provide an energy harvesting device having excellent efficiency and service life, which can recover electric energy from heat energy using the rotation-type actuator.
