Scientists at the Catholic University of Leuven have implanted an ID chip into a tooth to show how detailed personal information can be stored.
The scientists say the tooth chip will be useful to forensic scientists trying to identify bodies (even decomposed ones!) after natural disasters and terrorist attacks with numerous victims.
Dr Thevissen and his team have adapted an RFID tag which vets inject routinely into animals. It can carry information including a person’s name, nationality, date of birth, gender and national ID code.
Experiments showed that the tag withstood normal biting forces and worked after being heated to 450C and cooled. But repeated expansion and contraction of the tooth due to heating and cooling is a problem. So the design might be modified to include an insulating layer.
Remember the audio tooth implant concept?
