(a) Finite element simulation of strain of graphene ribbons with an attached proof mass with the ribbon’s width of 16 μm and single-side ribbon’s length of 3 μm under the conditions of the applied force of 1000 nN, Young’s modulus of 1 TPa, and residual stress of 0.3 GPa. (b) The strain of graphene ribbons with single-side length of 3 μm and different values of thickness versus the width of graphene ribbons under the conditions of the applied force of 500 nN, Young’s modulus of 1 TPa, and residual stress of 0.3 GPa. (c) The strain of graphene ribbons with the width of 3 μm and different thickness versus the single-side length of graphene ribbons under the conditions of the applied force of 500 nN, Young’s modulus of 1 TPa, and residual stress of 0.3 GPa. (d) The strain of monolayer graphene ribbons that have the width of 16 μm and single-side length of 3 μm changes with the applied forces under the conditions of different values of the residual stress in the graphene ribbons.
