A new type of diaper promises to put even the most inattentive parent in tune with a baby’s needs.

Developed by MIT researchers, the new smart diaper features an embedded moisture sensor that sends a signal to a smartphone or computer when a baby wets himself — giving the child’s caregiver an opportunity to change it before a rash starts to develop.

Developers say they hope to eventually use the technology in adult diapers as well. “Diapers are used not just for babies, but for aging populations, or patients who are bedridden and unable to take care of themselves,” says MIT’s Pankhuri Sen. “It would be convenient in these cases for a caregiver to be notified that a patient, particularly in a multibed hospital, needs changing.”

There’s no word on when the smart diaper will be available for consumers.
