A University of Exeter study has revealed that butterflies are helping to rapidly expand technology. The wings of the tropical blue Morpho butterfly have already inspired designs of new fabrics and cosmetics with other materials likely to benefit in the future.
The new research, which was carried out in collaboration with the General Electric Global Research Centre, revealed that the vapour molecules on the scales of the iridescent wings react differently on the top of the structures compared to the bottom. This enables their structure and surface to assist in the creation of applications such as security tags and protective clothing.
Pete Vukusic, Professor of Physics at the University of Exeter, said: “Understanding iridescence in butterflies and moths has revolutionised our knowledge of natural photonics. By using design ideas from nature we are able to work towards the development of applications in a range of different technologies. In this study the team discovered a new mechanism in photonic vapour sensing that demonstrates combined physical and chemical effects on the nanoscale.”
Tim Starkey, PhD student involved in the project, commented: “Performing collaborative research with leaders in their respective fields as a PhD student is a highly rewarding experience. Being involved in this research into butterfly wings has allowed me to present my results at international conferences and take extended trips to use research labs in the USA.”
