A Diaper That Texts You When It’s Soiled

Smart phones, smart TVs and now a smart diaper that will text you when it's soiled.  But how?

Having two children who are adults now, yes in the old days, we had to actually check to see if their diapers were soiled.  And sometimes that meant taking them apart which meant if it were a false alarm, that sticky tape would never stick the second time and you'd have to end up changing the perfectly good diaper anyway, unless you got out the packing tape.  And then, there were those times you didn't want to undo the tape and would opt to stick a finger or two up in it, and if the diaper was indeed soiled guess what would happen?  Sure would!  Those were the days.

Takao Someya and the University of Tokyo have developed an electronic circuit as thin as the plastic wrap you use in your kitchen that knows when a diaper is soiled before you do.  This team, in July 2013, announced that they’d come up with flexible circuits that could be implanted in the body to monitor body temperature or blood pressure or implanted on the roof of the mouth to be used as a touch pad for quadriplegics.  And now, this team believes this technology could be used in diapers.
