Attachment ability of combined biomimetic adhesive micro-textures of different shapes

Abstract There are various potential applications of biomimetic adhesive solutions including climbing robotic systems, mobile sensor platforms, and biomedical such as patches for external use. Achieving resistance to both normal tangential loads, however, is a critical issue that still needs be addressed. Some animals have developed exceptional attachment mechanisms based on combined fibrillar elements different shapes functions. Experimental investigation micro-textures tribological performances adhesion, friction, peeling needed apply this idea the design an artificial texture having similar “biomimetic” properties. In present study, we demonstrate combinations show increased efficiency under contact environments enable long-term solutions. Our work sheds light element inspired by nature their function ratio each element, well spatial repartition.
