▎ 摘　　要

NOVELTY - The sensor has a separating column fixed between with a top layer (1) and a bottom layer (4). The bottom layer is provided with three-dimensional (3D) mobile unit that is provided with a positive pressure graphene foam unit. The 3D mobile unit is fixed with an outer side of a graphite foam unit that is formed with a graphene support layer. A side of the graphene support layer is fixed with a cutting force sensing unit (3). A top part of the force sensing unit is fixed with a supporting layer (2). The 3D mobile unit is made of ultra-elastic material. USE - Graphene-based foam 3D force sensor. ADVANTAGE - The sensor has high sensitivity and high operational stability. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene-based foam 3D force sensor. Top layer (1) Supporting layer (2) Cutting force sensing unit (3) Bottom layer (4)
