Having just written about a thermometer board for home automation, I’ll stay on the temperature measurement topic, as I’ve found another thermometer that targets the medical field instead. Body temperature measurement at my local hospital is done under the armpit, which does the job in most cases, but more accurate temperature measurement of “deep body temperature” is normally achieved through rectal temperature measurement which is not as practical and comfortable for most people.
Daily measurements of deep body temperature can apparently allow physicians to better understand “biological clocks”. In practical terms, it means doctors would be able to know ovulation cycles, measure the fatigue degrees of athletes, and even prevent heat strokes and hypothermia. Seeing the impractically in the conventional method, Nakamura Lab at Tohoku University developed a “swallowable thermometer” for this purpose.
The swallowable sensor measures just 9.16mm in diameter, is allegedly perfectly safe to the human body, and is powered in the stomach using the same principle as the “Lemon battery” which utilizes magnesium (Mg) and platinum (Pt) electrodes to generate electricity in the acid environment of your stomach. The generated electricity is then stored in the capacitor of the thermometer allowing it to work for about 10 hours.
Temperature measurements are made every 30 to 60 minutes and wirelessly transmitted over a 10 MHz wireless connection. This means four main components are part of the swallowable thermometer: the temperature sensor, a wireless communication chip, a customized chip manufactured with 0.6μm-process withered CMOS technology, and a capacitor. Costs are expected to be under ¥100 (~US$0.9) in quantity.

It’s a pity they don’t added a camera to take some selfies 😉

Hope this works out – another use is with pets. Since they can’t talk it’d be nice to check their temp now and again without having to deal with the rectal thermometer.
Another stuped and useless thing.
Go buy it, idiots!
Is it single use ?
Like after they are pooped, can’t it be reused ?
So you don’t want to put thermometer up pets bum but happy to look through the poo for it!
not the same person? maybe first one is not happy but the true target person of the comment does not matter?
Wifi controlled explosive caps like these would be interesting to control bad guys, but still a way to last during decades with battery.
