Pixie Scientific has developed Smart Diapers (that's their actual name) that can send information to parents' smartphones. And no, it's not to let you know when the baby has peed or pooped. The smartness actually comes in the form of a color-changing QR code that parents can scan with their phones, and access health information via Pixie Scientific's app.
Pixie Scientific claims that the codes can detect if the baby is dehydrated, if its kidney functions are normal, if there's a urinary tract infection brewing, and even type 1 diabetes. Results from the app can be shown to the pediatrician, who can then give the child a proper diagnosis.
"You will use Smart Diapers instead of regular disposable diapers - there is nothing different," Pixie Scientific says in an FAQ. "But at least once per day you will scan a Smart Diaper with our phone app. The app will alert you if you should see a pediatrician or specialist."
The company is currently working with the Office of In-Vitro Diagnostics and the FDA to design a trial for approval.[via PSFK]
