Figure 4: Examples of transfer printing on complex surfaces.

Figure 4

(a–e) Photographs and/or magnified SEM images of various PI patterns with cilia (thickness=1.8 μm, width=10 μm, length=600 μm, density=30 mm−1) transferred onto a bandage (a,b), a tea strainer (c), a cotton swab (d) and a stone (e). Diluted PDMS solution (3.3 wt% in toluene) was used as glue. During the transfer process, the PMMA layer faces the target substrates except for the sample used in c-right. The PI patterns other than cilia were deposited with a Cr layer (thickness=70 nm) for high optical contrast.
