Printing thin-film circuits on flexible substrates may be ready for prime time with the introduction Thursday (Oct. 16) of what is claimed as the first commercial application of silicon ink. Kovio Inc. (Milpitas, Calif.) rolled out its silicon ink printing scheme at the Electronic Product Code conference in Chicago. The initial application will be RFID tags, with future applications ranging from printable sensors and flexible displays. Kovio claims its process can reduce the cost of RFID tags using ink-jet printing by as much as 15 cents to between 5 to 10 cents each. High-volume roll-to-roll printing could further reduce costs to less than a penny.
