Contactlessly activated RFID tag for tire
The provided is an electrical device having an antenna design for embedding electronic device during tire manufacturing to increase durability, fatigue performance and signal level. The electrical device includes an antenna having a suitable adhesive coating. The electrical device reduces operational process for tire manufacturing of RFID tag embedded tire by providing a ready to use tag which can be embedded within the tire without requiring further coating or other processing. Further, the rubber patching/layering process during preparation of the electrical device is eliminated.
