Recently, electrohydrodynamic (EHD) flows in electrolyte solutions have been observed and applied to micropumps. However, conventional EHD flows require to be applied at least several tens volts of electric potentials. A main purpose of this study is to develop a novel device which generates an EHD flow by the lower applied voltages inaqueous solutions. In the experimental system, current paths of cation and anion can be separated by using ion-exchange membranes with a pore. Both electrical and optical observations are carried out focusing on liquid flows in the pore. Consequently, EHD flows of several mm/s are observed by applying an electric potential of 2.2 V.
