ABSTRACT
The extraordinary climbing skills of gecko lizards have been under investigation for a long time. Here we report results of direct measurement of single spatula forces in air with varying relative humidities and in water, by the force-distance method using an atomic force microscope. We have found that the presence of water strongly affects the adhesion force and from analysis of our results, we have demonstrated that the dominant force involved is the capillary force.
Received for publication 2 May 2005 and in final form 6 June 2005.
The climbing ability of gecko lizards has attracted human attention for more than two millennia. The total clinging force produced by a Tokay gecko ...
