Parents of young children know all too well the vigilance necessary to keep everything dry down there throughout the day. Yet, for all the effort put in, there’s currently no effective way to tell whether your baby took a wee. Researchers at University of Tokyo are keen to change that, and they’ve developed a moisture sensor that can be embedded within diapers for real-time monitoring of kids’ bodily functions.
About the size of a playing card, the device works by measuring the change in electrical resistance between its electrodes. Besides the sensor, the device also includes a small radio transmitter through which parents and caretakers would be notified, in near real time, that a diaper change might be the thing to do.
In addition to monitoring for wetness, the researchers claim the same technology can be used to detect pressure, temperature, and maybe even blood oxygenation.
