Microsoft has invented a new smart diaper called the MS Diaper that uses sensors and an integrated circuit to monitor factors like wetness, temperature, and pressure. The diaper transmits this information directly to parents' Windows phones via an app so they know when it's time to change the diaper. The diaper can also detect issues like urinary tract infections. It comes in various colors and versions, including a high-end Gold version that converts waste to energy and can wirelessly charge other Microsoft products. The diaper aims to make parenting easier by eliminating the need to manually check diapers and allowing remote monitoring.
