Abstract: Provided is a method of fabricating magnetic cilia including the following steps. Step (A): A mold is provided in which a plurality of micro-channels are formed, wherein the aperture of each of the micro-channels is between 50 μm and 350 μm, and the depth of each of the micro-channels is between 500 μm and 3,500 μm. Step (B): A raw material is spread onto the mold and filled into each of the micro-channels, wherein the raw material includes a polymer and magnetic particles dispersed therein. Step (C): A heat treatment is performed to harden the raw material in each of the micro-channels into a magnetic cilium. Step (D): A mold release process is performed to isolate each of the magnetic cilia from each of the micro-channels.
