| Research Abstract |
In this research, a novel pumping mechanism, utilizing magnetic stress that generated by instantaneous magnetic filed gradient in ink, was proposed for the purpose to realize micro-patterns with functional materials on a small area surrounding of which is as high as several millimeters of uneven micro-structures. The capability of high pumping power and landing accuracy for the long flying distance of functional ink drop was evaluated. Structural design is the key for this pumping mechanism, and it was clear that there exist an optimum proportional relationship between the size of nozzle and ink channel span, and the angle to the channel entrance (75~80) in ink-tank, and arrangement of a non-magnetic thick layer in nozzle frontier (thickness: about half of the nozzle size) will be most effective to achieve the goal. Through fabrication process development including the heating mechanical derived new knowledge for the guidance of practical realization.
