Fabrication and electromechanical characterization of near-field electrospun composite fibers.

Room temperature deposition of circuitry may circumnavigate the need for conventional energy- and time-intensive fabrication of conducting materials. A unique advantage of near-field electrospinning is that it permits direct writing of conducting elements on soft bio-compatible substrates. The technique can be used to form precise conducting patterns with line widths ranging from sub-micron to tens of microns – feature sizes that are well suited to common biological cells. The new electrode deposition method also provides a way to incorporate less-deformable polymeric components in flexible electronics, through integrated design of circuits on insulating, elastically stretchable substrates.
