Acrylic-based adhesive patch leaves damage and residue on the skin surface and reduces adhesion in underwater environments. To overcome these problems, many researchers have developed bio-inspired adhesive patches to mimetic gecko feet and mushroom-shaped tips. However, without leaving chemical contaminants on the surface, the development of adhesive patches that can be repeatedly attached in wet and dry environments is still necessary. In this study, we report highly adaptable, biocompatible, and repeatable adhesive patches in various environments with microstructure inspired by the infundibulum of octopi suction cup. An octopi suction cup-inspired patches are fabricated by a simple molding process and controlling the meniscus of poly(urethane acrylate)(PUA) precursors using capillarity force. We performed the adhesion of the octopi suction cup-inspired patches using force gauge and showed excellent adhesion in Dry (19.7Kpa) and Wet (28.8Kpa) environments. |
