In previous study, we aim to develop innovative stirring technology (electric field stirring technology (EST)) applied abrasive control technique with AC electric field. This technology allows for stirring without contact by applying AC electric field to droplets. We examined observation of fundamental behavior and inside behavior for droplet by AC electric field and investigated the feature of EST as parameter frequency and voltage, quantitatively. As a result, the motion speed of particles in droplet was accelerated by this stirring technology. This EST was developed to the medical field and medical equipment was developed. In this study, we investigated about the temperature dependency under EST. Further, the efficiency of stirring was investigated to optimize the electrode shape and stirring conditions so as to speed up further. As a result, by the efficiency of stirring by the electrode obtained by concentrating electric field, higher quality results were obtained.
