Stiffness-gradient adhesive structure with mushroom-shaped morphology via electrically activated one-step growth.

ABSTRACT: Reptiles in nature have evolved excellent adhesion systems to adapt to complex natural environments, inspired by which high-performance bioinspired dry adhesives have been consistently created by precisely replicating the natural structures. Stiffness gradient, as a special feature evolved in reptilian adhesion systems, offers significant advantages in enhancing adhesion adaptation and stability. However, it remains a challenge to accurately replicate the geometrical morphology and soft-rigid composite properties of stiffness gradient structures, which limits the engineering applications of bioinspired adhesives. Here, a stiffness gradient adhesive structure with mushroom-shaped morphology via electrically activated one-step growth is proposed. Under the action of electric field, the liqui
