Chemometric brains for artificial tongues.

摘要: Abstract The last years showed a significant trend toward the exploitation of rapid and economic analytical devices able to provide multiple information about samples. Among these, so-called artificial tongues represent effective tools which allow global sample characterization comparable fingerprint. Born as taste sensors for food evaluation, such proved be useful wider number purposes. In this review, critical overview tongue applications over decade is outlined. particular, focus centered on chemometric techniques, extraction valuable from nonspecific data. basic steps signal processing pattern recognition are discussed principal techniques described in detail, highlighting benefits drawbacks each one. Furthermore, some novel methods recently introduced particularly suitable data presented.
