new sensor detects ethanol , warns consumers of food spoilage

ESPOO, Finland, May 6 (UPI) -- Researchers in Finland have developed a tiny sensor that can detect food spoilage. The sensor is small enough to be installed in the lining of food packaging and its signal can be read wirelessly by a mobile device like a smartphone.

The sensor works by detecting ethanol, a chemical byproduct of spoiling produce. Experiments showed ethanol and carbon dioxide were the two most volatile metabolite molecules given off by cut fruit.

Sensor findings are communicated via what's called a radio-frequency identification (RFID) tag. The RFID tag's messaging can be picked up by an RFID reader, which could be installed on a smartphone. The sensor can also communicate its readings optically, by changing colors.

Beware your produce bearing the mark of the beast!!!

Seriously though... This just seems completely unnecessary and will only translate into a markup on the already a rising cost of food.

I have an inbuilt sensor. It takes signals from my nose and my eyes and does some weird thing in my brain, et voila!
