离子液体电磁驱动研究

室温离子液体是新兴的绿色环保材料,具有液态温度范围广、不易挥发、良好的导电性和导光性,是微流控技术和光电子器件中良好的流体介质。离子液体的驱动是其能否在这些领域中应用的关键技术,也是应用中常常碰到的瓶颈。本文提出了一种电磁驱动离子液体的方法,无需机械移动装置,可双向驱动,稳定性好,并从离子液体本身性质出发,进行了微观和宏观两方面的理论分析及仿真计算,结果表明这种方式驱动力大,驱动速度较快,只需几伏的低压,能耗低,同时给出了一个最佳通道高宽比,最后分析了本方法存在的负面影响。

Electromagnetic Drive of Ionic Liquids

Ionic liquid is one kind of burgeoning green material.It is well electric and transparence,and has neglectable volatility,wide temperature range of liquid state,so it is a kind of good material in Microfluidics and photoelectronics,and so on.However,liquid actuation is a key technique and is the bottle-neck in applications.A way of electromagnetic drive is presented,where there is not any mechanical moving devices and its drive is bidirectional.By theory calculation and analysis,results indicate the driven pressure and the driven speed are also big values undering a few voltages,so it is low power cost pump,and there is an optimal ratio of height and width of channel.Electrothermal infection is analyzed and latency applications are given.
