Butterfly Wings Inspire New Technologies: From Fabrics and Cosmetics to Sensors

Morpho butterfly wings have surprising properties that could offer a variety of new technologies.

Scientific lessons learnt from these butterflies have already inspired designs of new displays, fabrics and cosmetics.

Now research by the University of Exeter, in collaboration with General Electric (GE) Global Research Centre, University at Albany and Air Force Research Laboratory, and funded by the US Defense Advanced Research Projects Agency (DARPA), has discovered that the physical structure and surface chemistry of the Morpho butterfly’s wings provides surprising properties that could offer a variety of applications ranging from photonic security tags to self cleaning surfaces and protective clothing and to industrial sensors.

Tiny tree-like nanostructures on the scales of Morpho wings are known to be responsible for the butterfly’s brilliant metallic blue iridescence. The study, published in the journal PNAS, found that vapour molecules adhere differently to the tops of these structures than to the bottom. This selective response to vapour molecules is the key to the range of possible bio-inspired technological applications.
