▎ 摘　　要

NOVELTY - A disposable sensing device for monitoring a hydrogen peroxide and a method of fabricating the same are disclosed in the invention. The disposable sensing device of the invention includes an insulative substrate and a working electrode, a counter electrode and a reference electrode, which all are formed on an upper surface of the insulative substrate. The disposable sensing device of the invention also includes an insulative layer and a reduced graphene oxide layer. The insulative layer is partially formed on the working electrode, the counter electrode, the reference electrode and the upper surface of the insulative substrate such that a first working surface of the working electrode and a second working surface of the counter electrode are exposed. The reduced graphene oxide layer is formed on the working surface of the working electrode an the second working surface of the counter electrode.
