Abstract
The disclosure relates to a hydrogen sensing device capable of visually detecting the presence of hydrogen through a color change according to a water-forming reaction by inducing the water-forming reaction between hydrogen and oxygen at the interface between a lower metal layer and a dielectric layer under a structure in which a lower metal layer, a dielectric layer, and an upper metal layer are sequentially stacked, and visually sensing the color change caused by the generated water.
