The Effect of an Applied Electric Field on Filament Stiffness

Mark Arsenault, Hui Zhao, Haim Bau, and Yale Goldman

The average, measured (symbols) and predicted (solid line) normalized root-mean-square displacement and the filamentís estimated tension (inset) as functions of the square of the electric fieldís intensity

The time-independent, electric field-induced flow field around the filament.


The filamentís stiffness increases as the applied electric fieldís intensity increases.


The electric field-induced tension is caused by electro-convection in the electric double layer enveloping the filament.
