Dry Adhesion of Artificial Gecko Setae Fabricated via Direct Laser Lithography
Biomimetics has introduced a new paradigm: by constructing struc‐ tures with engineered materials and geometries, innovative devices may be fabri‐ cated. According to this paradigm, both shape and material properties are equally important to determine functional performance. This idea has been applied also in the field of the microfabrication of smart surfaces, exploiting properties already wor...
متن کاملDynamic self-cleaning in gecko setae via digital hyperextension.
Gecko toe pads show strong adhesion on various surfaces yet remain remarkably clean around everyday contaminants. An understanding of how geckos clean their toe pads while being in motion is essential for the elucidation of animal behaviours as well as the design of biomimetic devices with optimal performance. Here, we test the self-cleaning of geckos during locomotion. We provide, to our knowl...
متن کاملEvidence for self-cleaning in gecko setae.
A tokay gecko can cling to virtually any surface and support its body mass with a single toe by using the millions of keratinous setae on its toe pads. Each seta branches into hundreds of 200-nm spatulae that make intimate contact with a variety of surface profiles. We showed previously that the combined surface area of billions of spatulae maximizes van der Waals interactions to generate large...
متن کاملLaser scanner for direct writing lithography.
A laser scanner and a stepping xy stage have been developed for direct writing lithography in the micron and the submicron range. System design is described and examples of exposed photoresist with a structure size of 1 microm are presented.
متن کاملRate-dependent frictional adhesion in natural and synthetic gecko setae.
Geckos owe their remarkable stickiness to millions of dry, hard setae on their toes. In this study, we discovered that gecko setae stick more strongly the faster they slide, and do not wear out after 30,000 cycles. This is surprising because friction between dry, hard, macroscopic materials typically decreases at the onset of sliding, and as velocity increases, friction continues to decrease be...
