“…Recently, a theoretical model of a fiber array with hierarchical structure was presented. [19] This model has taken both the seta and the terminal spatula in gecko's pads. The authors were able to predict the adhesive force of the system with good a good match with observations in the nature.…”

This work investigated the basic adhesion mechanisms of biomimetic elastomeric nanostructures using molecular dynamics simulation. The model based on a network of beads in the form of a specifically shaped pillar interacting with a flat substrate has captured the directionality of adhesion and the geometric asymmetry. The simulation results showed an excellent match with the experimental results of similar systems. Our results have explained the mechanisms behind strong adhesion and easy detachment. The stress concentration occurring when the displacement is imposed in the opposite direction to the angle of pillar tilt allows easy detachment as an unzipping effect. We have also found that by switching the angle of displacement one can increase or decrease the overall adhesion strength 4-folds or more. This work has potential implications for creating uniquely designed micro or nano-structures with desired attachment and detachment properties.

Insect attachment devices enhance adhesion to complex-geometry substrates by increasing the real contact area. In nature, insects mainly interact with plant surfaces that are often covered by 3D wax structures. Here, we describe, discuss, and give a mechanical interpretation of plant waxes and the possible fracture mechanisms of these wax structures during their interactions with the adhesive pads of insects. It is argued that these plant surface microstructures significantly influence insect adhesion through reducing the contact area and contaminating the insect pads.
