Moth eye implemented in windows

Yes, we admit that the post image is not really attractive. But come in and know an amazing development inspired by the nanostructure of moth eyes. As we said last week, biomimicry is incredible and can bring outstanding solutions to common problems. Why don’t we search for a solution to clean windows? That’s what researchers from the University College London thought. And they achieved it. Even more, they obtained extra properties for this discovery that make your windows better. Let’s see how a disgusting moth eye can help building technologies.

Moth eye: self-cleaning, energy-saving and anti-glare

Each time we read an article about biomimicry, we are more aware about the unbelievable possibilities that it offers to research and development. Does anybody like to catch moths and observe them in a mycroscope? We do believe that they are one of the most ugly and disgusting insects. If I could choose, I would select any other animal to study.

But let’s go back to the interesting developments that some brave researchers have obtained thanks to the analysis of moth eye. The result of the study is a nanostructure similar to that of moth eyes with three amazing properties:


The surface of this development is ultra-resistant to water. When rain hits it, small droplets are created that rolls over the window and remove dust and contaminants. This is possible thanks to the conical design of the nanostructure, what ensures that only a small part of the droplets are in contact with the window.

Glass is coated with a thin film of vanadium dioxide (only 5-10nm). It prevents thermal radiation scaping home in cold periods and avoids that solar radiation reaches your room in summer. Furthermore, this coating is cheaper than others commonly used.


The nanostructure gives the same anti-glare properties found in moth eye. It can cut the amount of reflected light to less than 5 percent. This is really useful in office buildings, where workers comfort can be disturbed by unexpected reflected lights.

As you can read, unexpected solutions can be found in nature. Moth eye is only one of the amazing examples that biomimicry can provide.
