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.

Recently, Electrostrictive polymers (EPs) are studied for micro-actuator, because of similarity of body tissue. Electrostrictive polymers (EPs) are based on the deformation of dielectric elastomer polymer in the presence of an electric field. Modeling of electrostrictive polymer has been studied, which is about voltage and displacement. And there are many parameters such as Young's modulus, voltage, thickness of EPs, pre-strain, dielectric, frequency and temperature which effect to movement of EPs. To do exact modeling, all parameters are included.In order to use as actuator, we accurately understood about the parameter that we refer above. And we have to execute modeling which parameters are considered. We used FEM in order to understand effects of parameters. Specially, because of pre-strain effects are very important, we derive the relations of stress and strain by using elastic strain energy. G

In this paper, the design and the construction analysis of an innovative nano-printer system are presented. A nano-printer system is comprised of automatic transmission parts and modified Active Fountain Pen Nano-lithography (AFPN) device. The patterning is made by a switch control method. For accurate control and fabrication of this device, the fluidic system is simplified by embedding a PZT (Lead Zirconate Titanate) plate in the nano-printer. And, without the cantilevers connecting the reservoir and tip, less energy loss is induced and the whole device becomes more sophisticated. In this paper, the critical channel size is decided for the whole simulation, and then the mechanical and piezoelectric properties of PZT are analyzed by the commercial software, ANSYS. The deformation of the PZT can be controlled precisely. Based on the analysis of the fluidic dynamics of this system, the line width of the pattern was found to depend on the mass of the meniscus formed at the tip. As long as the initial mass of the meniscus is set, the maximum patterning speed can be determined as well. Consequently the printing velocity of this system can be increased considerably beyond that of DPN (Dip-Pen Nano-lithography) or FPN (Fountain Pen Nano-lithography) because the mass of meniscus can be controlled by the applied voltage.
