Abstract
Improved RFID devices and manufacturing methods that utilize more efficient RFID designs, result in less manufacturing material waste and increased recycling opportunities, all without sacrificing RFID device performance, are disclosed herein. Some exemplary embodiments of the improved RFID device may make use of a thinner foil, a hollowed-out foil, a “no-strip” design, or a tessellated design that may reduce material usage. Other exemplary embodiments may use a lower-impact and/or biodegradable adhesive so as to improve aluminum recycling and lessen risks to the environment.
Claims5
A method of producing a radio frequency identification (RFID) device comprising:
- providing a foil and predetermining a plurality of RFID antenna patterns on said foil;
- tessellating the plurality of RFID antenna patterns based on the predetermining of the plurality of RFID antenna patterns on the foil;
- patterning the formed tessellation of the plurality of RFID antenna patterns, wherein patterning the formed tessellation of the plurality of RFID antenna patterns comprises printing a negative image of one or more of the plurality of RFID antenna patterns using an oil;
- and
- cutting the plurality of patterned RFID antennas from the foil to produce the RFID device.
