本文报道了在恒定直流电场作用下，水相微滴在油相中的旋转运动。液滴在正电极和负电极的适当几何布置下呈现旋转运动。旋转运动出现在某一临界电势之上，并且其频率随着电势的增加而增加。提出了一个简单的理论模型来描述这种旋转运动的发生，以及这种微型旋转电机系统的未来扩展的论点。(C)2010年美国物理学会。[doi：10.1063/1.3358385]
We report the rotary motion of an aqueous microdroplet in an oil phase under a stationary direct current electric field. A droplet exhibits rotary motion under a suitable geometrical arrangement of positive and negative electrodes. Rotary motion appears above a certain critical electric potential and its frequency increases with an increase in the potential. A simple theoretical model is proposed to describe the occurrence of this rotary motion, together with an argument for the future expansion of this micro rotary motor system.
