Project Title: Low-Cost and “Green” UHF RFID Tags
Hosting Institution: LSCM R&D Centre (LSCM)
Abstract: Today’s RFID tags are still too expense to be used for general products. Paradoxically, if everything around us is tagged with RFID labels, the tag itself will become a potential environmental hazard. Current tag materials are either not environmentally friendly or not decomposable in natural process.

We propose to develop innovative technologies to solve this puzzle -- RFID tags using environmentally friendly and other decomposable materials. On one hand, the RFID printing can be integrated into general product package printing process, thus the overhead cost is minimized; on the other hand, RFID will be fabricated using environmentally friendly materials, which can be decomposed during the recycling process. In order to put the low-cost and green RFID tags into reality, many technical challenges need to be solved, namely. 1) Direct Bonding Techniques, 2) Printed Antenna Designs; and 3) Conformal RFID.

In this project, new technologies will be developed. 1) Recyclability study of printed RFID with different conductive inks and substrate materials. 2) New bonding techniques that bond silicon chip directly onto printed antenna on paper and PET-type substrate. 3) New design and testing methodologies for RFID with printed antenna using conductive materials. 4) Conformal RFID labels integrated with product packages.
