Smart Materials and Structures

Nature offers a great source of inspiration for developing next generation optical applications. Many natural photonic structures are multifunctional and can be used in many applications.

The wing of the Morpho butterfly is a great example of multi-functionality. An evolutionary optimized nano-structure in the scales of this butterfly also gives a strong blue coloration and makes the wing hydrophobic. Because of these multiple features of the butterfly scales, biomimetic/replication of the micro/nanostructure especially on a large scale is extremely interesting for industrial applications.
