AI Technical Summary
Existing washable RFID tags have poor durability in harsh environments such as high temperature and rubbing, and are not compatible with RFID printers, which limits their application scenarios.
By employing an electromagnetic coupling structure between the chip and the circuit area, eliminating physical connections, and using electromagnetic coupling formed by conductive seams and matching rings, combined with the design of the printable layer and device area, the label's signal remains stable and compatible with printing equipment during high-temperature washing.
It maintains stable signal transmission in harsh environments while being compatible with RFID printers, thus improving the durability and efficiency of the tags.
