  4. Introduction on KET Electro ‐ Rheological Fluids What ERFs are ElectroRheological Fluids are polar nanoparticles (inorganic or organic) dispersed in a non-conductive fluid (e.g. silicon oil). Such materials drastically change their rheological characteristics at the application of an electric field (few kV/mm) passing from the liquid to a quasi-solid state at a speed of some milliseconds (1 ÷ 10 ms). www.eda.europa.eu 4
