Researchers at University of Jena, Germany, have created a small, gas-sensitive optical lens from hybrid glass material. The lens, just a few millimeters in size, changes its refractive properties due to a three-dimensional lattice structure with cavities for gas molecules. This "intelligent" behavior opens possibilities for applications in sensor technology, gas separation membranes, and logical circuits.
