Yes, it’s another online project to develop another wearable device for a baby… but this one specifically takes advantage of — get this — dirty diapers.

How? Well, as the developer Pixie Scientific says, “Kidneys filter specific solutes from blood into urine.  By taking useful data on these solutes, as well as by picking up on signs of bacterial activity from a wet Smart Diaper, we make use of something that would normally be thrown directly into the trash.  Smart Diapers alert you to certain conditions that require immediate attention and also track your child’s health for months, automatically looking for emerging trends in multiple combinations of parameters.”

Pixie Scientific has put the project up for backing here if you are interested.
