Researchers have created artificial "snot" to enhance the performance of electronic noses. The researchers, at Warwick and Leicester universities, have coated the sensors used by odour-sensing "electronic noses" with a mix of polymers that mimics the action of mucus in a human nose. This improves the performance of the devices, allowing them to pick out a more diverse range of smells.
