Printing sub-micrometer lines based on electrohydrodynamics

Printing techniques develop rapidly especially in the areas of electronics and biotechnology in these decades. In this paper, first we describe the use of electrohydrodynamics for jet printing the lines with the sub-micrometer resolution. It also presents the complex pattern printed by electrohydrodynamics jet printing with the same resolution combined with the automatic control technology. In the second part, we research on the parameters which affect the width of the printed lines by a series of experiments. Such experiments focus on the effect of voltage and distance between the tip of the nozzle and the substrate, in addition, concentration of the printed solution and the inner diameter of the nozzle are also considered.
