| Abstract: | Electronic nose(e-nose) is a a bionic sense of smell detector which has developed rapidly in the past dozens of years. An review of hot topics and key points of e-nose such as sensor arrays, signal processing and pattern recognition is given. It covers 3 kinds of sensor arrays and different methods of signal selection have been compared. Then, it focuses on the algorithm of pattern recognition, which ranges from linear and non-linear methods to supervised and unsupervised methods. Advantages and disadvantages of these methods have been analyzed in detail. At the meantime, the inadequate of e-nose are discussed, so are the future trends of e-nose. |
