A crowded bus or train is a disagreeable experience at the best of times, and the journey can be even more unpleasant if you fear you have bad breath. But help to tackle the problem is at hand, thanks to the latest in mobile phone technology. Researchers at Siemens in Germany have developed a smell sensor, to be built in to its next generation of handsets, which can detect bad breath. The microchip measuring less than one millimeter square triggers a high-pitched sound from the phone if exposed to bad or food-tainted breath.
