摘要
壁虎甚至在真空中都可以在垂直光滑的玻璃墙壁上纹丝不动和爬行 ,显然 ,这不可能是摩擦力和真空吸力所致 ,它不分泌任何液体 ,也不可能是通常的粘合剂作用。对壁虎脚足刚毛吸力的精确测定表明 ,壁虎腿与物体表面的吸力完全是范德华力相互作用。本文详细介绍了有关壁虎腿仿生研究的最新进展和可能的制备壁虎胶带的微制造方法。
Geckos,even in a vacuum,adhere firmly to polished glass.Obviously,two mechanisms of adhesion,friction and suction,have been ruled out.Adhesion by glue is also an unlikely mechanism,as skin glands are not present on the feet.Direct measurements of single setae force revealed that setae operate completely by van de Waals forces.The advanced developments of biomimicking gecko setae and the feasible methods of microfabricating gecko tape were introduced in this paper.
