The electrical and piezoresistive properties of graphene-modified Polymethyl Methacrylate (GmP) are investigated in this study. Results indicate that graphene content should be maintained between 1.0 wt% and 3.0 wt% to achieve a more stable resistance output while preserving a relatively low viscosity of the pre-hardening mixture. A constant input current is maintained to ensure compliance with Ohm's law regarding output resistance. As the graphene content increases, GmP exhibits a transition from a positive to a negative piezoresistive effect, showing more pronounced periodicity of the ∆R/R0 curve and enhanced stability during the unloading and rest periods. Furthermore, GmP shows increased piezoresistive sensitivity at higher load magnitudes.
