A device to single out spoiled food
Who are those of you who had never used his sense of smell to decide whether food was still good to eat? To decide if food is rotting often we rely on our sense of smell… a technique which leaves much to be desired.
If the nose is not terribly reliable, now a new technological device can be of help. A team of researchers in Nanjing, China, have developed an “artificial nose” capable of detecting food deterioration and thus avoid food poisoning.
Compact and easy to use, this device communicates with a nearby smartphone using Near Field Communication (Nfc). It is connected to a special sensor capable of detecting the presence of the substances that convey decaying food its characteristic odour. The sensors transmit all this information to the smartphone, guaranteed!
