Niko Münzenrieder submerges a ficus leaf in water containing pieces of a shiny metallic membrane. Using tweezers, he carefully moves one of these pieces on to the leaf of the houseplant. On lifting the leaf, the film sticks to it like glue. The post-doctoral researcher is demonstrating the special characteristics of this electronic component in the form of an ultra-thin membrane, which he has helped to develop. “These new thin-film transistors adhere to a wide range of surfaces and adapt perfectly,” explains the physicist.
