Silicon Ink

Silicon ink has been a dream for decades, and now it’s a reality. Kovio, based in Milpitas, California, has addressed the problem in part by layering silicon ink with a solvent made of nanoparticle powder. The company hopes its first product, a radio-frequency identification tag with a printed chip in it, will one day replace the bar code as a low-cost identification stamp that can be placed on almost any product.
