Abstract
Droplets on highly deformable, elastic surfaces exhibit unusual wetting behaviour. The deformability of the substrate alters the contact angle with respect to Young’s law, while spreading dynamics is fundamentally different from that on rigid surfaces. Here we report recent experimental and theoretical progress, and highlight some of the salient features of the solid’s surface tension.
