This smart mouth guard monitors the wearer's health by tracking chemicals in their saliva and sending health updates to their smartphone.
Researchers at the University of California, San Diego, developed a high-tech mouth guard that tests levels of uric acid, lactate and cortisol in the wearer's saliva in order to monitor the health of the individual. Any imbalance is reported to their connected smartphone, computer or tablet via a supporting app.
The ability to continually monitor health in a non-invasive manner could be very useful for individuals who don't have any identified health issues but are nonetheless exposed to high-risk situations. For example, the mouth guard could be used to keep athletes at optimal health during games or be worn by soldiers during training and in the field.
