Adhesive mechanisms and the role of positional adjustment on tree frog toe pads

Objective: this paper aims to evaluate the adhesive and frictional properties of the keratinised epithelium on the adhesive pads of tree frogs. Modeling methods: two modeling methods have been developed. One of these methods involves the implementation of discrete fibres in a relatively compliant material matrix while the other method involves...

On the mimicking of geckos and tree frogs for adhering to soft substrates

<b>Background</b>: Soft-tissue grip is a challenge in minimally invasive surgery. Grasping instruments used in clinical practice require high pinch forces in order to generate sufficient grip for manipulating soft tissue without slipping.<br/>In nature, several animals employ adhesion in order to grip on, not only hard, but also soft substrates....
