(a) Photographs of the measurement set-up (a-left) and a substrate (a-right) used in the peel test. (b,c) Peel force profiles of the substrates with various cilia length scales (b-top), densities (b-bottom) and concentrations of the PDMS glue solution in toluene (c). (d) Photographs of the measurement set-up and a substrate used in the shear test (d-top) and the shear force profiles of the substrates with or without cilia (thickness=1.4 μm, width=10 μm, length=600 μm, density=30 mm−1) and various concentrations of PDMS glue solution in toluene (d-bottom). Shear rate is set to be 0.3 mm s−1. The textile used in these mechanical tests is the same as that used in Fig. 2.
