Overview

How can a textured surface maintain contact when liquid accumulates between an adhesive and the skin?

Biological inspiration, surface architecture and wearable application.

My Work

Surface design

Contribute to wet-adhesion research combining tree-frog-inspired pillars with honeybee-inspired frames in a micro-nano hierarchical surface.

Interface mechanics

Investigate liquid-film splitting and confined wetting to connect surface geometry with normal and shear adhesion.

Hierarchical surface design

Honeybee-inspired concavities and tree-frog-inspired pillars form the textured wet adhesive interface.

Liquid-film observation

Interface observations show how liquid distributes around the microstructures during contact.

Normal and shear adhesion

Mechanical comparisons connect microstructure geometry and wetting conditions to adhesive performance.
