In this research, an ESC that can handle curved/rough surface is developed. An ESC consisting of compliant electrostatic inductive fibers which transform according to the profile of surface has been proposed for such use. The fundamental idea of comes from the inspiration based on gecko which can quickly adhere and move on walls or ceilings having curved/rough surface; it is well-known that the tip of such surprising capability is due to the hierarchical fiber micro/nano-structure on the finger-tips. The potential and feasibility of the fiber ESC proposed are shown by prototyping electrostatic inductive fibers and new type of ESC consisting of the fibers that can work for curved or rough surface through both experimental and theoretical approaches.
