Researchers in Germany have discovered that a butterfly’s transparent wing eliminates most reflections at any angle. This natural source of inspiration for technology could be ideal for phones, camera lenses and any other device where glare is a problem. The technology works because of irregular, nanoscopic structures on the glasswing of the butterfly. Whilst the surface is still being refined in the labs, the prototypes are already self-cleaning and water repellent, which would avoid the need for current anti-glare coatings to be applied as done presently.
This would be a big improvement for people using their smartphone and take much of the strain from those working outdoors and having difficulty in clearing seeing content on their device.
