  • Plasmonic hydrogen sensors have limited sensitivity due to broad spectral features. Here, the authors use a particle swarm optimization algorithm to inversely design a plasmonic metasurface based on a periodic array of Pd nanoparticles, and demonstrate hydrogen detection limit of 250 ppb.

  • Detecting hydrogen gas in humid air is an unresolved challenge of significant importance for the safe implementation of hydrogen (energy) technologies. Here, authors demonstrate how the use of neural networks enables the sensing of hydrogen in highly humid air with a detection limit of 100 ppm.

  • Sensing hydrogen by the change in plasmonic response upon metal hydride formation is safe, but trace gas poisoning and low sensitivity can occur. Here, a PdAu alloy/polymer sensor is poison resistant and can sense 3 ppm H2 with a response time of 1 s.
