Researchers develop hydrogen sensor inspired by butterfly wings

A team of researchers at RMIT University in Melbourne have developed a prototype hydrogen sensor influenced by the wings of butterflies.

This influence is portrayed within the colloidal crystals that make up the sensor which are likened to the small bumps located on the surface of butterfly wings. 

According to an article in The Engineer, the sensor, which is light-powered, could prove to be a breakthrough in the diagnosis of gut disorders as it was able to detect small volumes of gas on people’s breath. The device also has the ability to ascertain hydrogen leaks.

“Hydrogen has the potential to be the fuel of the future but we know safety fears could affect public confidence in this renewable energy source,” said Dr Ahmad Kandjani, who is the co-lead researcher for this study. 

“By delivering precise and reliable sensing technology that can detect the tiniest of leaks, well before they become dangerous, we hope to contribute to advancing a hydrogen economy that can transform energy supplies around the world.”
