Research Abstract |
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.
