Printed electronics in RFID expected only later

Printed electronics has the potential to transform the RFID industry, if and when they gain sufficient market acceptance and find appropriate applications. But their impact - contrary to some expectations - will not be significant for some years to come.
"Printed electronics - antennas, transistors and batteries - could eventually change the dynamics of the RFID industry," says Sara Shah, an industry analyst at ABI Research. "Applied directly to materials such as corrugated cardboard, they would allow manufacturers and distributors to create their own 'smart packaging' and bypass the whole long RFID tag production chain."
Printed antennas that operate in the HF and UHF bands are available now, and eventually a large proportion of UHF RFID antennas could be produced by printing. But their ideal market, UHF supply-chain management, is itself growing more slowly than originally expected. Printed transistors on the other hand, which only operate with quite low performance in the LF band and conform to no standard, are not available yet.
"When printed transistors arrive in 2008 they will not be able to compete with silicon transistors," says Shah. "With their low frequency operation and incompatibility with existing readers, they will not be suitable for open loop supply chains, until standards emerge for item-level LF tagging. They should, however, carve out their own market for tagging very low-cost, non-critical objects in the meantime."
Printed transistors might find a role in closed-loop asset management solutions. That sector, ABI Research believes, could produce viable levels of demand, especially since end-users have seen much success in this application with conventional tags. Cheaper tags have the potential to speed a return on investment. Printed batteries will eventually become part of the RFID market as well, enabling the addition of temperature, humidity and light sensors to RFID tags. But ABI Research says that this market will not develop until much later.
ABI Research (www.abiresearch.com) has a new study available; 'Printed Electronics in the RFID Tag Industry' that examines the technologies, applications and time frames for their introduction.
