Scientists at Philips Research have created a fully functional 13.56 MHz RFID tag based entirely on plastic electronics. In contrast to conventional silicon-chip-based RFID tags, a plastic electronics RFID chip can be printed directly onto a plastic substrate along with an antenna without involving complex assembly steps. This could pave the way for the packaging industry to replace existing barcodes by a low-cost RFID tag that provides individual packages with a unique item-level identification code – something not feasible with current barcode technology.
Radio Frequency Identification (RFID) is an automatic identification method, based on remotely retrieving information via radio waves from miniature electronic circuits called RFID tags. Philips has now realized the first plastic-electronics-based tag that is capable of transmitting multi-bit digital identification codes at 13.56 MHz – the dominant industry-standard radio frequency for RFID tag applications. As an additional demonstrator for the technology, scientists at Philips Research have also developed a 64-bit code generator, showing the practicality of building plastic electronic circuits with the complexity required for item-level tagging.
Performance results for these circuits will be presented at this year’s International Solid-State Circuits Conference (ISSCC, February 5-9, San Francisco, CA, USA) in a paper that will also be awarded the conference’s Beatrice Winner Award for Editorial Excellence.
