The current-voltage characteristics and the electrical responses of the electrorheological (ER) fluids were measured under DC electric field conditions. The test fluids consisted of microsphere particles with various moisture levels (in a range of 1500 to 7000ppm wt.%) dispersed in a dimethylsilicone oil (at 30wt.%). In these fluids, the relationship between the current density and electric field strength could roughly be fitted with sinh functions suggesting ionic conduction. The forces of cohesion between individual particles in the ER fluids were considered using the mathematical model in which the current passes through the surface layer of the particles. The current-force relationship predicted by the theory was compared to experimental results for the test fluids. It is shown that the particle conductivity in ER fluids plays a dominant role in the mechanisms of the ER effect.
