Abstract
Although biomimetic technologies for dry reversible adhesion seem to be maturing, the costs, complexity, and time expenditures associated with the current template-based molding techniques call for research on other fabrication methods. In this paper, we report a novel cost-effective, simple, and flexible drawing-based technique for manufacturing the soft elastomeric thin-film-based microstructures needed for successful implementation of the principles of biological shear-activated adhesion. Several different types of adhesive microstructures are fabricated, and the best of them demonstrate shear-driven amplification of pull-off force by a factor of 40, which significantly outperforms known molded analogues. A simple gripper based on a manual center-clamping vise is shown to enable pick-and-place manipulation of various flat and curved objects of everyday use.
