Abstract

The intention of this research was investigated the line width that is written by NFP (nano fountain pen) using active membrane pumping in order to understand how to control it. The relationships between velocity of tip, concentration, and ink diffusion with line width were studied; it was found that variation of velocity of tip and concentration of ink affect directly to line width. Therefore, this study is shown a model of verifying line width through two conditions: velocity and diffusion.
