Abstract: Resistivity property of graphite based MRE is demonstrated in the present research. In this paper, a study on the force sensitive property by using a composite of graphite (Gr) and magnetorheological elastomer (MRE) is suggested where graphite powder was used as a conductive element in the composite. The carbonyl iron particles and graphite powder were mixed in the silicon rubber to produce the Gr-MRE composite. The resistivity properties are then identified from a designated test rig that delivers different magnitude of the applied force on the sample. Results showed that the resistivity of the material decreased as the applied force increase from 700 to 1000g, where the magnitude of the resistance decreases approximately 79 to 66%. By having higher magnetic flux density in the material, the stiffness of the Gr–MRE could possibly be controlled depending on the magnitude of the force.
