Machine olfaction: pattern recognition for the identification of aromas

Describes a portable pattern recognition system (PRS) based on embedded technology for intelligent volatile detection (electronic nose). This instrument is designed to hold advanced signal processing and digital communications services in a contained size. A summary of the hardware is presented followed by an application to the identification of extra virgin olive oils. The instrument of the example is able to classify eleven different classes of Spanish olive oil with a 79% of accuracy and relatively simple pattern recognition techniques.
