Transparent conductors with specific patterns are essential for touch screens as sensing electrodes. Among them, metal grids are a kind of optimal alternative for traditional transparent conductors, while moiré patterns hinder metal grids in the application of display planes. Nevertheless, random or aperiodic pattern grids can avoid the patterns. A series of bioinspired random (BR) grids is demonstrated that can avoid moiré patterns and exhibit great optoelectronic performance comparable to indium tin oxide (ITO). The BR grids comprising random hexagons originate from biological networks with line arrangements that are random and aperiodic. They are fabricated through a controllable and highly efficient method of patterning foams, and are composed of close-packed silver nanoparticles (AgNPs). This type of grid has potential to extend applications of high-transparent functional devices. Anti-moiré random grids with irregular hexagons inspired by the networks of veins in a dragonfly's wings are easily fabricated using a patterning foams method. The proposed method can quickly assemble silver nanoparticles into a variety of complicated random grids. Experiments show that the as-fabricated grids can effectively avoid Moiré patterns compared to regular grids. These anti-moiré grids hold promise for applications in liquid crystal displays.
