Attachment systems in the nature have revealed various exquisite multiscale architectures such as gecko’s locomotion, beetles’ wing fixation, octopuses’ sucking and crawling. In particular, the hierarchical hexagonal structures in the tree frog’s adhesion have the capability of enhanced adhesion forces on the wet or rough surfaces due to conformal contacts and water-drainable micro channels. Here, we report tree frog-inspired patches using artificial 3-dimensional structures to form reversibly enhanced adhesion against highly curved and rough surfaces in dry and wet condition. To investigate the adhesion effect of micro-channels, we changed the arrangement of microstructure and spacing gaps between micro-channels. In addition, we introduced the patches to enhance to conformal contacts on the various rough surfaces such as skin and organs. Furthermore, we demonstrated skin-attachable in-vitro diagnostics which can measure the tiny forces such as pulsation and mussel-stiffness. |
