The invention discloses a graphene pressure sensor material. The graphene pressure sensor material includes an elastic matrix and a graphene three-dimensional network structure arranged in the elasticmatrix in a penetrating mode. At least part of graphene in the graphene three-dimensional network structure is intrinsic graphene or reduced graphene oxide. The graphene three-dimensional network structure has a first direction and a second direction, and the first direction and the second direction are perpendicular to each other. In the first direction, the graphene three-dimensional network structure is cut and divided into a plurality of substantially equal-thickness sub-layers substantially parallel to the second direction, and the mass of the graphene in each of the sub-layers is not completely the same. The invention further discloses a pressure sensor and a preparation method of the graphene pressure sensor material.
