For monitoring hydrogen partial pressure, optical sensors have a particular safety advantage due to absence of wiring in operation area. Here authors show hysteresis-free, reproducible change in optical transmission in palladium-capped hafnium hydride films over six orders of magnitude in hydrogen partial pressure.
