Because all children have their own twitter and are willing to have transmitters clipped onto their crotches.

Utterly disgusting and typical corporate rubbish in the name of money. Interesting how the pilot program is in Brazil and not the US.

I agree with Fahrenheit451, however, as an ex-care worker, I can see the advantage for care staff looking after elderly residents.
Typically, in a British care home, elderly diaper wearers (they are referred to as 'pads' rather than diapers/nappies when worn by adults) are disturbed by carers once or twice a night to see if they are wet. This clearly affects sleep quality.
And elderly people with speech or cognition issues (eg dementia) are not always able to alert carers when they are wet. So this technology could potentially aid carers, but should be properly risk assessed, and not be a replacement for normal good caring practice.

This is easily as stupid an idea as the fridges with cameras and iphone apps to call you about the state of the fridge contents during your busy day. I have cared for kids of various sizes and generally there is no great mystery or surprise in noticing that someone's diaper has reached it's design load limits. Also, transnational corporations try ideas in various markets to see if stuff flies without risking an outcome like New Coke.

Great, now parents are paying the Corporations for the luxury of expanding DARPA's nearly-ubiquitous NSA sensor-net into their own children's pants. Could it be a sign of impending societal implosion?

If you're gonna be connected then you should be really connected! What about the "other" end?

How about one that just connect via bluetooth? Why do we need twitter? I like the idea for adult care though - it might even help some old people who have just lost sensation - if it were, you know, a little more private.

Yea... I just had to log in for this. If any article deserves this it's this one:
WFT!!!! WFT is wrong with some people... Really, F'n psychos

All joking aside --- I could see a bigger and significantly more important application for this in geriatric care. Use this to monitor and then alert nursing staff when patients have poo/peed in their diapers so they can be changed quickly rather than having them sit for hours in their on excrement.

Great invention, but I think The parents should have better check on their children than a mobile app.
