Abstract:
1. An actuator having a cylindrical structure, wherein discoidal electrodes are buried in the cylindrical structure in parallel at a specified interval to the bottom of the structure and narrow tubes penetrate the structure through multiple fine pores in the structure wherein liquid is present between the fine pores and narrow tubes; a first band pattern comprising an organic molecular layer comprising at least one group having a positive charge and a second band pattern comprising an organic molecular layer comprising at least one group having a negative charge, said first band pattern and said second band pattern alternately arranged on the surface of the narrow tubes; the interval of the bands is same as the interval of the discoidal electrodes when an electric field is applied to the discoidal electrodes; and a gap between the surface of the organic molecular layer of the narrow tube penetrating into each fine pore and an inner wall of the fine pore being extremely small; and the cylindrical structure comprising an insulator.
