Abstract

Abstract : In article number 2001125, Huawei Chen and co‐workers develop a strong wet attachment surface with hierarchical pillars and nanocavities on top inspired by the unique micro–nano structure on tree frog toe pads. Such a bioinspired surface creates interfacial liquid vertical self‐splitting and self‐sucking effects to generate a strong boundary friction without external preloaded normal force. This research gives potential for broad applications in various fields, such as medical devices and wearable sensors.
