Fabrication of a biomimetic controllable adhesive surface by ultraprecision multistep and layered scribing and casting molding

Wedge-shaped microstructures have the ability to reproduce the excellent adhesive properties of geckos’ feet because of their unique anisotropic structure. In particular, the controllability of the wedge-shaped microstructures on adhesion is beneficial to the undisturbed grasp or the capture of space targets. However, the problem currently remains of how to process it efficiently and with high quality. Here a strategy called ultraprecision...
