A temperature-sensitive thermal cutoff fuse RFID tag is provided with a bimorph element and thin conductive bridges positioned on an RFID tag substrate that can react to all changes in storage temperature conditions. The bimorph element is configured and positioned so that when it bends in response to one or more predetermined temperatures, the bimorph element will break one of the conductive bridges and cause an open circuit that can be detected when the RFID tag is interrogated by a sensor. The temperature-sensitive thermal cutoff fuse RFID tag can provide high and low temperature information about numerous stored objects such as food, medicine, chemicals, batteries, explosives and munitions. Multiple temperature conductive bridge cutoff fuse RFID tag arrangements and methods for notifying the user when a required storage temperature has been reached with a passive temperature-sensitive thermal cutoff fuse RFID tag. |
