Abstract: Embodiments of the present invention relate to an electrical switch or sensor. In one embodiment, the electrical switch or sensor comprises a first electrical pole conductively coupled to a first side of a layer of variable resistance material. A second electrical pole is conductively coupled to a second side of the variable resistance material. The first side of the variable resistance material positioned distal to the second side of the variable resistance material. The variable resistance material comprises a polymer comprising a glass transition temperature of no higher than about 10° C. The first electrical pole and/or the second electrical pole comprise an electrically conductive ink or coating having a dispersion of graphene sheets. The graphene sheets completely comprise fully exfoliated single sheets of graphene. The graphene sheets comprise a lattice having heteroatoms incorporated therein and/or functional groups attached thereto.
