A surface treatment method is provided. A surface treatment method comprising steps of providing a first and a second conductors; applying an electrical field between the first and the second conductors; enclosing the first and the second conductors with a material whose viscosity is varied with an intensity of the electrical field; actuating the first and the second conductors such that the first and the second conductors are in a relative motion with respect to each other; and varying the intensity of the electrical field.
