More Information
Summary:This disclosure describes RFID tags configured to fracture when heated, such as when exposed to threshold levels of electromagnetic energy. In some instances, the RFID tags include materials that expand when heated for the purpose of stressing metal antenna traces of the RFID tags. When under stress from these expansion materials that bond to the antennas (e.g., thermoplastics), these antennas may fracture, thus lessening the risk that the dangerous arcing will occur from the electromagnetic energy, such as when an item and corresponding tag are placed in a microwave oven.
