Electrically driven formation of droplets of conducting fluids combined with electrostatic control of droplet trajectory forms the basis of a method that can be used to print liquids with micron resolution. This talk describes basic aspects of this approach and its use in printing a variety of fluids, including suspensions of single walled carbon nanotubes, solutions of conducting polymers, and range of dielectric materials. Simple devices, such as organic transistors and light emitting diodes, demonstrate some of the patterning capabilities. Advantages and disadvantages compared to conventional ink jet printing will be described.
