介绍了用于氢检测的金核/钯壳超材料。当超材料层暴露在2%的氢混合物中时，观察到来自超材料层的反射和透射率都发生了30%以上的变化，这对于肉眼来说是明显的，因为超材料所传输的光的亮度发生了变化。这种传感器应该对涉及氢的过程的安全做出贡献。
Gold-core/palladium-shell metamaterials for hydrogen detection are presented. The more than 30% change in both the reflection and transmission from the metamaterial layer that is observed when the layer is exposed to 2% hydrogen mixture is clearly noticeable to the naked eye as a change in the brightness of light transmitted by the metamaterial. This sensor should make a contribution to the safety of processes involving hydrogen.
