Scientists have developed a nappy device which can send emails or text messages to parents to inform them that a nappy change might be needed, say its developers.
According to the scientists, the device can also detect a baby's heart rate, temperature and can let you know whether your child is happy, grumpy or upset.
In fact, the system works by detecting moisture on the baby's skin, which indicates that the nappy has begun to leak, the ‘Daily Mail' reported.
A special thread woven into the fabric senses electrical signals on the skin. When the skin becomes moist, the signal becomes stronger because the liquid conducts electricity. This information triggers an email or text alert, say developers.PTI
