(a) Finite element simulation of resonant frequency 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 resonant frequency of graphene ribbons with an attached proof mass with single-side ribbon length of 3 μm and different values of thickness of graphene ribbons versus the width of the graphene ribbon 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 resonant frequency of graphene ribbons with an attached proof mass with the ribbon’s width of 3 μm and different values of thickness of the graphene ribbons 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 resonant frequency of monolayer graphene ribbons with ribbon’s width of 16 μm and single-side ribbon’s length of 3 μm changes with the applied forces under the conditions of different values of the residual stress in the graphene ribbons.
