Summary: Robust and reversible wet attachments are crucial for medical engineering and wearable electronics. The discovery of unique hierarchical micro-nano fibrous pillars on Chinese bush crickets shows a wet friction that is approximately 3.8 times higher than that of tree frog's bulk pillar. By introducing a nano-fibrous pillar array covered with thin films, the contact stress at the interface shifts from compressing to stretching, leading to the formation of more stable and larger nano-liquid bridges and a friction enhancement of about 1.9 times.
