Reentrant feature widely exists in natural structures ranging from mushroom, overhang,
undercut, trapezoid, sphere, spatula and taper to sharp edge, and has triggered a …

Polydimethylsiloxane (PDMS)—the simplest and most common silicone compound—
exemplifies the central characteristics of its class and has attracted tremendous research …

Reversible adhesion is the key functionality to grip, place, and release objects
nondestructively. Inspired by nature, micropatterned dry adhesives are promising …

Joining two materials with an adhesive is an extremely common activity, but is most often
irreversible. However, emerging and current applications ranging from consumer and …

The remarkable ability of geckos to climb and run rapidly on walls and ceilings has recently
received considerable interest from many researchers. Significant progress has been made …

For biologically inspired dry adhesives, the fibrillar structure of the surface requires sufficient
flexibility to form contacts and meanwhile high rigidity to maintain stability. This fundamental …

Small living organisms such as lizards possess naturally built functional surface textures that
enable them to walk or climb on versatile surface topographies. Bio-mimicking the surface …

Electronic skins endow robots with sensory functions but often lack the multifunctionality of
natural skin, such as switchable adhesion. Current smart adhesives based on elastomers …

Electrostatic flocking, a textile engineering technique, uses Coulombic driving forces to
propel conductive microfibers toward an adhesive‐coated substrate, leaving a forest of …

Geckos have developed a unique hierarchical structure to maintain climbing ability on
surfaces with different roughness, one of the extremely important parameters that affect the …
