Abstract
The purpose of this paper is to find a suitable sampling method for portable electronic noses. For this reason, two sampling methods, namely classic dynamic sampling (CDS) method and bio-inspired breathing sampling (BBS) method, were studied using a portable e-nose designed by us. In order to test the performance of the two sampling methods, the same data processing procedures were employed to handle the sampled data, and two classification methods were used to identify seven kinds of Chinese liquors. The results show that the BBS not only spends shorter sampling time with fewer samples per second, but also obtains higher classification accuracy. Therefore, the proposed BBS is more suitable for portable e-noses.
