📚 This Smart Diaper Uses RFID to Alert Parents When Babies Must Be Changed

If you’re a parent, you certainly know how important it is to change a wet diaper at the right time. If you’re not a parent, then don’t worry because it won’t be long until you’ll have to do it too. But if you’re lucky enough, this system developed by MIT researchers could be more commonly used by the time you become a parent and determining if a diaper needs to be changed would only become a sensor’s problem. More specifically, these researchers have created a new low-cost diaper that could issue an alert whenever dampness is detected. While the concept of smart diapers isn’t necessarily new, the MIT engineers say their idea surely is. A concept detailed this week explains that instead of using expensive sensors, their low-cost smart diaper would rely on an RFID tag that doesn’t cost more than a few cents. “The sensor consists of a passive radio frequency identification (RFID) tag, th... ...
