LCD disc shows baby temperature

A disappearing smile could help save the lives of thousands of babies across the developing world, its makers say. The smile is seen on a disc stuck onto the skin which monitors temperature. When babies are warm enough, mothers will see a green spot with a smile - but if they are too cold, the smile disappears and the spot turns black. The LCD disc has an adhesive back, so it can be stuck securely onto the skin.
