Highly Permeable Skin Patch with Conductive Hierarchical Architectures Inspired by Amphibians and Octopi for Omnidirectionally Enhanced Wet Adhesion |
| 초록 |
Amphibian adhesion systems can enhance adhesion via hexagonal architectures, enabling peel resistance and drainage against wet and rough surfaces. In addition, an octopus has suction cups with convex cup structures for strong adhesion in various conditions. Highly permeable, drainable, and reusable skin patches with enhanced pulling adhesion and omnidirectional peel resistance, inspired by the microchannel in the toe pads of tree frogs and convex cups in the suckers of octopi, are presented. By investigating geometric parameters of microchannels, a simple model to maximize peeling strength via a time-dependent zig-zag profile and an arresting effect against crack propagation is developed. Octopus-like convex cups are employed on the surfaces to improve adhesion on skin in sweaty and flowing water conditions. rGO nanoplatelets coated on the surface is controlled to utilize the patches as flexible electrodes which can monitor biosignals without delamination from wet skin under motion. |
