Study on Electric Conductivity Under Tensile Condition of MCF Rubber for Haptic Robot Sensor

Abstract

By the application of our developed magnetic intelligent fluid, MCF (magnetic compound fluid) to the silicon oil rubber, we could make the MCF rubber highly sensitive to temperature and electric conduction. It is useful for the element material in haptic robot sensor and et al. By mixing Cu and Ni particles in the silicon oil rubber and by applying a strong magnetic field to that, it can have high density of magnetic clusters. We clarified the electric resistance under tensile strain. The experimental results could be explained by using the relation of electric resistance among apparent cross sectional area and length of the particles, guessed from the results by SEM of the formation of the clusters.
