In the era of information communication technology (ICT), RFID has been going through
tremendous development. RFID market surpassed $7.6 bn in 2012. RFID technology has the potential of replacing barcodes due to its large information carrying capacity, flexibility in operations and versatilities in applications. However, the penetration of RFID technology is hindered due to its high price tag. Many projects had been stalled only due to the cost of the tag. The application specific integrated circuits (ASICs) in RFID tags are the most expensive item. Fully printable chipless tags will provide competitive advantages over barcodes. If chipless RFID can be made less than a cent, the chipless RFID market will surpass $4 bn by 2019.

With unique features of identification, tracing and tracking capabilities, RFID also gives value added services incorporating various sensors for real-time monitoring of assets, public installations and people from various backgrounds. Chipless RFID sensors for temperature, relative humidity, pH, impact and presence of noxious gas monitoring have opened new prospects. The market will grow to tens of billions. Since the chipless tag has no intelligence, the signal processing is done only in the reader. Therefore, a full new set of requirements and challenges is needed to be incorporated and addressed, respectively, in the chipless RFID tag reader. This seminar addresses the development made in new smart materials for new chipless RFID tags and sensors, reader architecture and signal processing techniques at Monash University.



Dr. Nemai Chandra Karmakar (S’91–M’91–SM’99) obtained the BSc(EEE)
and MSc(EEE) from BUET, Bangladesh in 1987 and 1989, respectively, M.Sc. degree in (EE)
