摘　　要：Autonomously self-healing, reversible, and soft adhesive microarchitecturesand structured electric elements could be important features in stable and versatilebioelectronic devices adhere to complex surfaces of the human body(rough, dry, wet, and vulnerable). In this study, we propose an autonomousself-healing multi-layered adhesive patch inspired by the octopus, which possessself-healing and robust adhesion properties in dry/underwater conditions.To implement autonomously self-healing octopus-inspired architectures, adynamic polymer reflow model based on structural and material design suggestscriteria for three-dimensional patterning self-healing elastomers. In addition,self-healing multi-layered microstructures with different moduli endowsefficient self-healing ability, human-friendly reversible bio-adhesion, and stablemechanical deformability. Through programmed molecular behavior ofmicrolevel hybrid multiscale architectures, the bioinspired adhesive patchexhibited robust adhesion against rough skin surface under both dry andunderwater conditions while enabling autonomous adhesion restoring performanceafter damaged (over 95% healing efficiency under both conditions for24 h at 30℃). Finally, we developed a self-healing skin-mountable adhesiveelectronics with repeated attachment and minimal skin irritation by laminatingthin gold electrodes on octopus-like structures. Based on the robust adhesionand intimate contact with skin, we successfully obtained reliable measurements during dynamic motion under dry, wet, and damagedconditions.
