Butterfly wing-based technology creates new developments for energy use

Professor Shin Jung Hoon’s team from the Department of Physics and the Graduate School of Nanoscience and Technology at the Korean Advanced Institute of Technology (KAIST) produced a display that mimics the structure of the morpho-butterfly’s wings using glass beads.This could be used to make very bright displays with low energy consumption. This new technology can also be utilized for anti-counterfeit bills, as well as coating materials for mobile phones and wallets. The procedure was through the random alignment of differently sized glass beads on a very small scale. This created a disordered substrate, on which they placed a thin periodic film on top using the semiconductor deposition method. This combination of disorder and periodic order created the morpho-butterfly-like structure over a large area.
