In current medical diagnostics, skin patches often experience reduced adhesion forces or even complete failure due to perspiration, thereby compromising the quality and stability of biosignal monitoring. Inspired by hexagonal prism structure tree frogs frame honeybees, we designed a honeybee-treefrog bionic hierarchical patterned surface (HTP) fabricated with polydimethylsiloxane (PDMS), integrating advantages both organisms significantly enhance wet performance. The performance HTP under various wetting conditions was systematically evaluated constructing different types sizes adhesive surfaces. results indicate that can effectively drain excess liquid from contact interface maintain high force. demonstrated remarkable improvements in normal shear force, increased approximately 8-fold 4-fold, compared nonpatterned Through theoretical modeling experimental validation, reduces height bridge at via film self-absorption effect, enhancing adhesion. Additionally, is further improved air embolism which formed stagnant pockets low fluid volume conditions. Beyond superior performance, also exhibited excellent drainage capability reusability. Applied patches, showcased its potential for electrocardiogram (ECG) monitoring, demonstrating strong biocompatibility detection capabilities, offering new solutions wearable devices.
