Three-dimensional graphene foam for highly sensitive pressure sensors

Abstract

In this paper, the three-dimensional compressible graphene foam was synthesized via a simply reduction and self-assembly process. The as-prepared three-dimensional graphene foam shows ultralow density, high porosity and great mechanical compressibility and stability. With unique electrical feature and high sensitivity as well as robust mechanical strength, the as-fabricated three-dimensional graphene foam poses the great potential as elastic pressure sensor materials.
