Exploiting the electromagnetic coupling to estimate the close motion of UHF-RFID tagged objects

Curated by Roxtron — RFID & NFC manufacturer. Visit roxtron.com

Researchers have developed a method to track the micro-movements of objects by analyzing electromagnetic coupling variations between adjacent UHF-RFID tags. This technique enables high-precision proximity sensing without specialized hardware, allowing manufacturers to implement granular motion monitoring in dense industrial storage or retail environments using existing infrastructure.
