Morphologies of ER fluid at different times, and field strengths. ((a)–(c)) Side view of the ER fluid at different times under 1200 V/mm. The column structures are stable even after 10.5 hours. (d) When the electrical field strength decreases to 300 V/mm, the columns are no longer suspended in the liquid and they sedimentate to the bottom of the cell.
