Taking care of a young baby can be challenging, especially for first-time parents. Wouldn’t it be nice if parents have a way to realize when their baby was ready to poop or pee? The University of Tokyo has developed a flexible wireless organic sensor system that alerts parents when it detects a trace of wetness in a diaper. These sensors monitor wetness, pressure, and temperature inside the diaper. This technology could also work for adult diapers. It could certainly make life easier for some folks.
