Looking for a more effective way to track your circadian rhythms, based on your core body temperature?

From Singularity Hub . com: “Ingestible sensor chips are an idea a little easier for most people to swallow. Here are three examples. Camera pills, which pass through your digestive tract taking pictures and transmitting them out are available from Given Imaging. Available to your doctor, that is. You may have seen the commercials. But two other swallowable sensors are now on the scene. The CorTemp thermometer pill from HQInc travels through your digestive tract wirelessly transmitting your core body temperature. Useful for athletes today, and for those with occupational exposure to high temperatures. Again, this mimics a singly-capable Tricorder device where hand-held electronics receive wireless signals about the temperature inside your body.”
