What Is a Tooth Tattoo?

Dental tattoo is an electronic chip sensor that can detect germs in the human body. It was successfully researched by scientists at Princeton University in March 2012. It can collect bacterial information in the mouth of the patient and breathe it through the built-in wireless The network signaling device is reported to the medical staff responsible for monitoring.

Tooth tattoos are made from a high-tech graphene material. Graphene is a single-layer thin film of carbon atoms. It is the thinnest but hardest nanomaterial in the world. Its surface is very sensitive and it is easy to adhere to other substances. Therefore, a chip sensor made of this material can be easily inlaid on the tooth surface, and can easily pick up bacterial molecules like a "nylon buckle".

Dental tattoo technology can be applied to the army or hospital. For soldiers injured in battle or patients with weakened immune system functions, medical personnel can monitor the infection and spread of bacteria through dental tattoos.

In April 2012, scientists at Princeton University were applying for a patent certificate for this invention, hoping to apply it to clinical treatment as soon as possible. [2]
