Researchers at RMIT University in Melbourne, Australia, have developed a light-activated hydrogen sensor that detects hydrogen leaks before they pose safety risks.
Based on bumpy microstructures that imitate the surface of butterfly wings, the sensor can measure tiny amounts of gas on people’s breath, for diagnosing gut disorders.
It can also detect hydrogen at concentrations from as little as 10 parts per million molecules (for medical diagnoses) to 40,000 parts per million.
Co-lead researcher Dr Ylias Sabri said the prototype was scalable, cost-effective and offered a total package of features that can’t be matched by any other hydrogen sensor on the market.
