In this study we show the influence of surface roughness on gecko adhesion on both the nano- and macroscales. We present experimental data for the force necessary to pull off single spatulae from hard rough substrates and also detail observations on living geckos clinging to various surfaces. Both experiments consistently show that the effective adhesion shows a minimum for a root mean square roughness ranging from 100 to 300nm.
在本研究中，我们展示了表面粗糙度在纳米和宏观尺度上对壁虎附着力的影响。我们给出了从硬粗糙基底上拉下单根刚毛所需力的实验数据，还详细观察了活壁虎附着在各种表面上的情况。这两个实验一致表明，对于均方根粗糙度在100至300纳米范围内，有效附着力呈现最小值。
