Chipless RFID, printed electronics, and low-cost tag research for high-volume item-level tracking.
No original coverage in this desk yet.
The Shenzhen demonstration exhibits a battery-free temperature tag that transmits data at rapid speeds and high density. This performance metric reflects a specific capability in proximity sensing rather than a new standard for general identity management.
Read the briefA high school researcher has developed a chipless RFID tag made from conductive MXene that can be printed directly onto plastic packaging and dissolved during standard industrial recycling washes. This innovation addresses a critical barrier to circularity by enabling automated polymer sorting without contaminating the final recycled material, offering a low-cost, sustainable alternative to traditional silicon-based tags.
Read the briefResearchers have developed a patch-based multi-tag chipless RFID configuration designed specifically for high-density batch-level identification. This development enables cost-effective tracking of multiple items simultaneously without the silicon overhead of traditional RFID, offering a scalable solution for high-volume logistics and inventory management where item-level cost is prohibitive.
Read the briefA new conductive ink formulation allows for the screen-printing of RFID antennas and wireless power transfer (WPT) coils that maintain high conductivity through multiple industrial laundry cycles. This development removes a primary barrier to the mass adoption of smart textiles by ensuring electronic performance does not degrade during routine cleaning. For manufacturers, this enables the production of durable, wash-resistant e-textiles for healthcare and hospitality sectors
