Some scientists at the Catholic University of Leuven have semi-succesfully accomplished an interesting feat—embedding ID information in human teeth.

The ID tags would be used to store personal information about individuals and would enable forensic teams to identify bodies in catastrophic events.


The ID tag being used is an adapted RFID tag, similar to the ones used in animals for tracking purposes. The tag is able to withstand the repetetive biting force, along with resistance to extreme heat and cold, but there are still concerns with the tag being able to withstand the expansion and contraction of tooth due to sporadic heating and cooling. Creepy, no?
