A Review of the State of Dry Adhesives: Biomimetic Structures and the Alternative Designs They Inspire

摘要: Robust and inexpensive dry adhesives would have a multitude of potential applications, but replicating the impressive adhesive organs many small animals has proved challenging. A substantial body work been produced in recent years which illuminated mechanical processes influencing interface. The especially potent footpads tokay gecko inspired researchers to develop examine an diverse collection artificial fibrillar adhesives, though study tree frogs insects demonstrate that successful designs come forms. This review discusses current theoretical understanding mechanics, including observations from biological systems lessons learned by attempts mimic them. Attention is drawn particular growing contingent exploring ideas are complimentary or alternative for designs. fundamentals compliance control form basis made composite “smart,” stimuli-responsive materials shape memory polymers. An overview fabrication test techniques, with sampling performance results, provided.
