...Peter H. Niewiarowski; Alyssa Y. Stark; Ali Dhinojwala ABSTRACT The natural clinging ability of geckos has inspired hundreds of studies seeking design principles that could be applied to creating synthetic adhesives with the same performance capabilities as the gecko: adhesives that use no glue...

...Alyssa Y. Stark; Jocelyn Ohlemacher; Ashley Knight; Peter H. Niewiarowski ABSTRACT The gecko adhesive system has been under particular scrutiny for over a decade, as the field has recently attracted attention for its application to bio-inspired design. However, little is known about how...

...Andrew G. Gillies; Amy Henry; Hauwen Lin; Angela Ren; Kevin Shiuan; Ronald S. Fearing; Robert J. Full The role in adhesion of the toes and lamellae – intermediate-sized structures – found on the gecko foot remains unclear. Insight into the function of these structures can lead to a more general...

...Alyssa Y. Stark; Timothy W. Sullivan; Peter H. Niewiarowski SUMMARY Despite profound interest in the mechanics and performance of the gecko adhesive system, relatively few studies have focused on performance under conditions that are ecologically relevant to the natural habitats of geckos. Because...

... reaction forces of geckos on different slope surfaces. The FMA consists of 16 3D sensors with resolution to the mN level. At the same time the locomotion behaviour of geckos freely moving on the FMA was recorded by high speed camera. The reaction forces acting on the gecko's individual feet measured...

...Jonathan B. Puthoff; Michael S. Prowse; Matt Wilkinson; Kellar Autumn SUMMARY Geckos owe their remarkable stickiness to millions of dry setae on their toes, and the mechanism of adhesion in gecko setae has been the topic of scientific scrutiny for over two centuries. Previously, we demonstrated...

...Geoffrey A. Manley; Johanna E. M. Kraus SUMMARY We describe exceptional high-frequency hearing and vocalizations in a genus of pygopod lizards ( Delma ) that is endemic to Australia. Pygopods are a legless subfamily of geckos and share their highly specialized hearing organ. Hearing...

..., the adhesive on the toes of geckos is made of β-keratin, a stiff material with E at least four orders of magnitude greater than the upper limit of Dahlquist's criterion. Therefore, one would not expect aβ-keratin structure to function as a PSA by deforming readily to make intimate molecular contact...

...K. Autumn; A. Dittmore; D. Santos; M. Spenko; M. Cutkosky SUMMARY Directional arrays of branched microscopic setae constitute a dry adhesive on the toes of pad-bearing geckos, nature's supreme climbers. Geckos are easily and rapidly able to detach their toes as they climb. There are two known...

We challenged geckos ( Hemidactylus garnotii ) to climb up a smooth vertical track that contained a force platform. Geckos climbed vertically...
