(a) The Fe-PDMS mixture is poured onto a glass plate and bubbles removed in vacuum. (b) Narrow-gauge wire is used to create a constant-width spacer. A second glass plate is placed on top of the Fe-PDMS. (c) A weight is used to compress the Fe-PDMS sheet to ensure uniform thickness, and the assembly is placed in an oven to cure. (d) The top glass is pried away after curing. (e) The cured Fe-PDMS sheet is sliced to make cilia. (f) A rectangular PDMS chamber is cut where each cilium is to be mounted. (g) A drop of uncured PDMS is used on each side of the gap to glue the cilium in place. (h) Excess Fe-PDMS is used as support material (removed after curing) to create a gap between the cilium and the slide and ensure the cilium will be parallel to the slide. (i) A final curing step completes the fabrication of the cilia system.
