Development of soft liquid process for fabrication of micro-functional device

本研究的目的是通过微凋落物液体颗粒的生成和操作过程，建立制造微观功能器件的基本技术。我们还尝试将这些技术应用于流体动力学的新测量系统的开发，如超剪切速率区域的动态表面张力和流变学测量。首先，我们利用麦克斯韦应力建立了飞行液体粒子的飞行操纵技术，麦克斯韦应力是由液体和周围介质的介电性差异引起的力。该技术可以应用于飞行粒子轨迹的偏转、加速度和液滴振荡的非接触激发。利用这些技术，我们构建了混合液体颗粒的飞行制备工艺，并成功制备了可用于给药系统的微胶囊。

The purpose of this study was to establish the fundamental techniques to fabricate microscopic functional devices through the generation and manipulation processes of the pico-litter liquid particles. We also tried to apply these techniques to the development of new measurement system of the fluid dynamics, such as the dynamic surface tension and rheology measurement in hyper shear rate region. First, we established the in-flight manipulation technique of the flying liquid particles using the Maxwell stress, which is the force induced by the difference between the di-electricity of the liquid and surrounding medium. The technique can be applied to the deflection of the trajectory of the flying particles, acceleration, and the excitation of the droplet oscillation in a noncontact manner. With these techniques, we constructed an in-flight fabrication process of the hybrid liquid particles and successfully made micro capsules, which can be employed for the drug delivery system.
