Understanding the mechanism behind the gecko adhesive system has recently received significant interest because of the potential of creating synthetic dry adhesives inspired by nature and evolution. Since van der Waals forces are responsible in the adhesion mechanism of geckos, the hierarchical structure and geometry of the system become critical as opposed to surface chemistry. This poster demostrates (1) the role of geometry (Peel Zone Model) in the enhancement of adhesion, and (2) the influence of the spacing parameters (Stacking Model) in determining the maximum achievable adhesion. Insights provided by the proposed models will potentially guide the design of future synthetic dry adhesives inspired by the gecko adhesive system.
