초록

자연계에 존재하는 다양한 생명체 중 몇몇은 벽이나 천장을 자유자재로 걸어다니거나 뛰어다닌다. 이러한 생명체 중 대표적으로 Tokay Gecko는 그 발가락 표피에 수십억개의 주걱모양의 나노헤어를 가지고 있으며, 이러한 나노헤어는 부착하고자 하는 표면과의 원자수준의 끌어당기는 힘을 발생시키게 되며 이 힘을 이용해 접착제 없이 부착력을 얻게 되는 것이다. 최근 $7{\sim}8$년 동안 많은 연구자들은 이를 모방한 건식부착물의 제작 연구를 수행하고 있으며, 본 논문에서는 이러한 연구들의 개관을 통해 향후 연구방향에 대해 논의하고자 한다.

In nature, some creatures have the ability to walk vertically or upside down on various natural surfaces. One of them, Tokay Gecko has billions of nano-hair at the epidermis of its digital. These nano hairs makes atomistic attractive force to the surface, therefore, it could walk and run on the vertical or upside surfaces. Recently, many researchers tried to fabricate the dry adhesive structure mimicking the nano-hair structure. in this study, I tried to survey these studies to discuss the direction of future fabrication works of dry adhesive structures.
