Pixie Scientific from New York City has recently debuted their new Smart Diaper, which can detect diseases when your child urinates. Using traditional urine test strips, the company has designed their Smart Diapers with these strips built-in to a QR code. When the area surrounding the QR code comes in contact with urine, it tests for any disease. Parents can then scan the QR code with the accompanying smartphone app and keep track of any disease or problems.
