Can you please point us to a research body working on temperature-sensitive RFID tags? We need to obtain tags that would stop working at a specific temperature.

Harry,

I am unaware of any company that offers a tag designed to stop working at a specific temperature, or of any research organization developing such a tag. My guess is that no one has seen a need for tags with this capability because they would assume that once the tag reached a specific temperature, it could transfer that information to the reader, which would signal another program to take action.

If you definitely need to have tags that would no longer function at a specific temperature, you would likely need to speak to a tag company that could custom-design and produce such tags for you. This probably could be accomplished by manipulating the characteristics of the solder connecting a chip and an antenna so that it would melt at a given temperature, thus disconnecting the chip from the antenna and rendering the tag inoperable. Good luck—I hope you find what you’re looking for.
