A sub-cell with bandgap of around 1 eV is required to improve the efficiency of multi-junction solar cells beyond what is possible with legacy triple-junction architectures [1]. Solar Junction Corporation has been focused since 2007 on the developmen

Geckos are highly efficient climbers and can run over any kind of surface with impeccable dexterity due to the typical design of their hierarchical foot structure. We have fabricated tilted, i.e., asymmetric, poly(dimethylsiloxane) (PDMS) microflaps

The importance of loading and unloading procedures has been shown in a variety of different methods for biological dry adhesives, such as the fibers on the feet of the Tokay gecko, but biomimetic dry adhesives have yet to be explored in a similar man

Geckos are able to adhere strongly and release easily from surfaces because the structurally anisotropic fibers on their toes naturally exhibit force anisotropy based on the direction of articulation. Here, semicircular fibers, with varying amounts o

Most geckos can rapidly attach and detach from almost any kind of surface. This ability is attributed to the hierarchical structure of their feet (involving toe pads, setal arrays, and spatulae), and how they are moved (articulated) to generate stron

The discovery and understanding of gecko ‘frictional-adhesion’ adhering and climbing mechanism has allowed researchers to mimic and create gecko-inspired adhesives. A few experimental and theoretical approaches have been taken to understand the e

The articulation of gecko-inspired synthetic adhesives has received less attention than fiber geometry and fabrication method in the literature. In this paper, systematic variation of approach angle, shear length, and retraction angle have been perfo

A highly reusable synthetic gecko-inspired adhesive has been developed using angled polydimethylsiloxane (PDMS) semicircular microscale fiber arrays, retaining up to 77% of the initial adhesion force over 10,000 repeated test cycles against a flat gl

Geckos have developed a unique hierarchical structure to maintain climbing ability on surfaces with different roughness, one of the extremely important parameters that affect the friction and adhesion forces between two surfaces. Although much attent

A synthetic adhesive inspired by the gecko should replicate the important properties found on the animal, but does not need to be a direct copy of its system. This paper describes the fabrication and testing of micron-sized vertical and tilted rectan
