Abstract

See full text

Aspects of the present disclosure relate to a security device, in particular, a multilayered security device. The multilayered security device includes a substrate layer having a first substrate. The substrate layer attaches to the product. The multilayered security device also includes a graphene layer. The graphene layer has a first continuous graphene sheet that is made of a monolayer of covalently-bonded carbon atoms. The graphene layer also forms, in response to exposure to a verification stimulus, a contrasting pattern with respect to an exposed substrate area from the substrate layer.
