Inkjet, screen-printing and gravure are three printing technologies that are commercially used for printing electronics, flexible displays, and RFID tags. However, the smallest features that can be printed using inkjets today is about 20 microns, although this is still sufficient for many applications, its scale leaves it far behind today’s silicon electronics. We introduce the next generation of printed devices that prints features at today’s silicon electronics line width, which is 1000 times smaller (about 20 nanometers). The technology uses directed assembly based printing at the nanoscale to make products that fully take advantage of the superior properties of nanomaterials. This printing technology can print metals, insulators and semiconductors (including III-V and II-VI), organic and inorganic materials into micro and nanoscale structures and circuits on flexible and rigid substrates. The technology is 1000 times faster than inkjet based printing and costs 10-100 times less than conventional fabrication. In this presentation, we show the applications of this technology in electronics, sensors and meta materials applications.
