Harry Dewick-Eisele asked 3 years ago

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.


= = =


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.

There are passive RFID tags that report temperature. All you have to do is ignore the readings if they come in over a certain temperature. We supply the tags and the RFID readers in such applications.

What temperature is needed please? We have temperature sensing RFID Tags as do others, but there are limits to their temperature limits.

Hi Mark, Neil and James
Thank you very much for your replies. I can see that the industry has developed so much further since I last had anything to do with RFID.
We are trying to monitor multiple items in a building during night time from a single occupied reception. If any of the locations shows a temperature increase above say 80 degree Celsius, we need an alarm to appear in the reception, identifying which item is experiencing a temperature increase. RFID appears attractive as it would not require wiring.
Is there any way we could continue this conversation, please? To go into more details I would need an NDA, though.
