Electrohydrodynamic printing of silver nanoparticles by using a focused nanocolloid jet

As a direct write technology, the electrohydrodynamic printing of silver nanoparticles by using a focused nanocolloid jet is introduced. In this letter, two categorized types of examples of two-dimensional patterning were printed by using the electrohydrodynamic printing method. A spiral-type inductor was printed to demonstrate the feasibility of the electrohydrodynamic printing as a fabrication process. The printed spiral inductor produced 9.45 mu H and exhibited approximately five times larger resistivity (9.5 mu Omega cm) than that of bulk silver after the sintering process. Then, complex geometries having square- and round-shape patterns were also printed. (c) 2007 American Institute of Physics.
