When a DC field is applied to the electrodes, the drop charges and rises within the'liquid, then falls down as its charge leaks away, due to the finite elechic relaxation time of the liquid. The drop keepsbouncing as long as the high voltage applied remains above a minimum threshold. We focus our study on the dynamics and the deformation of a water drop before the lift-off and during its motion. Electrodes of different materials are used in order to illustrate the role of interfacial energy between the electrode and the water. |
