Saw this on the news yesterday, it looks pretty cool. It's a small device that fits inside of a gelatin capsule and passes through your system. There is another device which is the monitor and it's designed to measure body temp during endurance activities. How cool would it be to have this device in your pocket and be able to check throughout the day your body temp on T-3 and clen , it measures it to the decimal. Sounds cooler than carrying a thermometer around. It's safe and has been used by over 30,000 people so far.
