Latest Invention: Spectrometer - Small Device that Analyzes the Freshness of Food

Share

A group of researchers from the Fraunhofer Institute of Photonic Microsystems (IPMS) looks forward to presenting a small prototype spectrometer that can be used to estimate factors like water and protein level in different foods.

The invention will thus allow people to buy such products as fruits by considering not only their exterior but how fresh they are on the inside.

The technology will be officially presented at the Sensor+Trade fair in Nuremberg in the period between May 22 and 24. It would be interesting to note that the micro electromechanical system (MEMS) spectrometer is able to analyze any food, even if it is covered with a thin packaging film.

You only have to point the device on a piece of fruit, for instance. The system will examine the spectrum of infrared light by comparing it with data found in a database.

Such technology could be integrated into smartphones and can be found useful when making buying recommendations.

According to researchers' expectations, the technology could appear on the market in 3 to 5 years. It will be able to read not only food but drugs, cosmetics and forgery detection as well.
