Abstract
Disclosed herein is a method for manufacturing a hydrogen sensor, the method comprising the steps of: disposing a thin film made of a transition metal or an alloy thereof on a surface of elastic substrate; applying a tensile force in a repetitive manner to the elastic substrate to form a nanocrack on the thin film disposed on the surface of the elastic substrate; and injecting hydrogen gas into the formed nanocrack and then removing the hydrogen gas to form a nanogap, wherein the tensile force in the step of forming a nanocrack is applied to an extent that the elastic substrate has a tensile strain of 25% to 100%.
