Scientists combine gas sensors and NFC tags to deliver rotten food warnings to consumers

The ultimate ‘smell test’: Device sends rotten food warning to smartphones — American Chemical Society — “The scientists created a nanostructured, conductive, polymer-based gas sensor that can detect substances called biogenic amines (BAs), which give decomposing meat its bad odor. They embedded these sensors into NFCs placed next to meats. After the meats had been stored for 24 hours at 86 degrees Fahrenheit, the researchers found that the sensors successfully detected significant amounts of BAs. The sensors then switched on the NFCs so they could transmit this information to a nearby smartphone.”






A biometric ring could replace your passwords, cards and keys

A biometric ring could replace your passwords, cards and keys — Engadget — “With a fingerprint sensor on the inside, it can confirm that you’re the authorized user. Then, you slide on the ring, and an onboard IR optical sensor makes sure the device is still on your finger. As long as you have not taken it off, you can authorize transactions with a tap of your hand… Token transmits the authentication signal over NFC in most situations.”
