Beetle adhesive hairs differ in stiffness and stickiness: in vivo adhesion measurements on individual setae

JMR Bullock, W Federle - Naturwissenschaften, 2011 - Springer
Leaf beetles are able to climb on smooth and rough surfaces using arrays of micron-sized
adhesive hairs (setae) of varying morphology. We report the first in vivo adhesive force …

Fabrication and analysis of gecko-inspired hierarchical polymer nanosetae

AYY Ho, LP Yeo, YC Lam, I Rodriguez - Acs Nano, 2011 - ACS Publications
A gecko's superb ability to adhere to surfaces is widely credited to the large attachment area
