Can we inkjet print an RFID tag? People have been wanting to replace barcode with RFID in auto-ID for ages now. If we can print a high-performance transistor could we inkjet-print conductors into a coil on the same substrate?
It would be tough because you would need a lot of transistors, at least a few thousand even for the simplest of RFID tags. In this study they only managed to print about 200. Given that you can buy RFID stickers for ~0.1 USD the economics don't really stack up.
