A novel design of micro/nano-structured materials provides outstanding mechanical and electrical properties for wearable applications. Inspired by the structures and functions of biological systems, we developed hierarchical ZnO nanowire arrays based electronic skins capable of detecting both static and dynamic stimuli like skin mechanoreceptors. The effective stress transmission of microridges between the epidermis and dermis gave insights into designing spacer-free and wearable triboelectric sensors. For the ultra-conformal electronics, we suggested the highly compliant and printable magnetic paste for on-skin magnetic-field sensors. Finally, mimicking biological origami, we demonstrated soft and intelligent magnetic origami actuators that allow shape-reconfigurable and self-controllable actuation. Such excellent characteristics of novel-structured materials facilitate more interactive features in futuristic wearable electronics.
