在直流电压作用下，油相中的固体颗粒表现出两种运动：旋转运动和旋转运动。根据斯托克斯阻力和粘性力矩对其作为微电机的动能输出进行了量化。利用这种方法，本文讨论了微电机输出能量与外加电压和溶质浓度的关系。对系统的电能输入进行了计算，并对能量转换效率进行了讨论。微电机系统能量转换效率的量化使研究人员能够在一个共同的基础上讨论具有不同粒子、溶液、实验装置等的微电机系统。这使得微电机在不同研究之间的比较成为可能，并将加速微电机系统的发展。
A solid particle in an oil phase under a direct current voltage exhibited two types of motions: revolving and spinning. Its kinetic energy output as a micromotor was quantified based on Stokes’ drag and viscous torque. With the use of this method, the dependence of a micromotor’s energy output on the applied voltage and solute concentration are discussed in this paper. The electric energy input to the system is calculated, and the energy conversion efficiency is discussed. The quantification of energy conversion efficiency of micromotor systems enables researchers to discuss the micromotor systems with different particles, solutions, experimental setup, etc., on a common base. This makes the comparison of micromotors between different studies possible and will accelerate the development of micromotor systems.
