Cilia are hairlike organs that are found on the surface of small organisms in water such as paramecia. The movement pattern of cilia is known as a metachronal wave, which realizes efficient fluid transport. Our study aims to mimic the metaclonal wave of cilia and apply it to micro pumps. Artificial cilia fabricated using elastic material dispersed with magnetic particle could generate a metachronal wave by applying a rotating magnetic field. We fabricated five types of artificial cilia and conducted comparative experiments. The experimental results showed that the different flow was made depending on the design parameters of the cilia, and the cilia with metachronal wave improved the flow rate compared with cilia with synchronous motion.
