About the Cover:

A hierarchically arrayed octopus-inspired pattern (h-OP) formed on piezoelectric composite patch devices is developed. The h-OP enables robust wet adhesion to skin because its dome-like architecture achieves interfacial adhesion by generating capillarity-assisted suction stress. The h-OP devices demonstrated stable adhesion and high energy generation efficiency, even on the wet skin.
