Nanotechnology and sunlight clear the way for better visibility

A new coating developed by ETH researchers prevents fogging on transparent surfaces. Rather than using electricity, the coating relies on sunlight to heat the surface.

Anyone who skis, wears glasses, uses a camera or drives a car is familiar with the problem: if you come into a humid environment from the cold, your eyewear, camera lens or windshield can quickly fog up.

Researchers at ETH Zurich have now developed a new transparent material coating that greatly reduces this effect. Just a few nanometres thick, their durable coating is made of gold nanoparticles embedded in non-conductive titanium oxide.

The ETH scientists are now planning to bring their new method to market, in collaboration with a partner from industry.
