電子舌（又稱(cheng)味覺指紋分析(xi)(xi)系統、滋味分析(xi)(xi)儀、味道檢(jian)測儀），型號(hao)(hao)SuperTongue，是一(yi)種(zhong)主要由傳感器陣列、信號(hao)(hao)采(cai)集電路(lu)、基于模(mo)式(shi)識(shi)別的數據處理方法組成的現(xian)代化定(ding)性定(ding)量分析(xi)(xi)檢(jian)測儀器。電子舌原理基本如下：味(wei)覺(jue)傳(chuan)感器陣列(lie)模(mo)擬生物(wu)系(xi)(xi)(xi)統(tong)(tong)中的舌頭，對不同“味(wei)道”的被(bei)測(ce)溶液進(jin)行(xing)感應；信號(hao)采集(ji)系(xi)(xi)(xi)統(tong)(tong)模(mo)擬神經感覺(jue)系(xi)(xi)(xi)統(tong)(tong)采集(ji)，被(bei)激發的信號(hao)傳(chuan)遞(di)到電腦(nao)模(mo)式識別(bie)(bie)系(xi)(xi)(xi)統(tong)(tong)中；模(mo)式識別(bie)(bie)系(xi)(xi)(xi)統(tong)(tong)即(ji)發揮生物(wu)系(xi)(xi)(xi)統(tong)(tong)中大腦(nao)的作用對信號(hao)進(jin)行(xing)特(te)征提取，建立模(mo)式識別(bie)(bie)模(mo)型，并(bing)對不同被(bei)測(ce)溶液進(jin)行(xing)區(qu)分辨識。

電(dian)子舌（味覺(jue)指(zhi)紋(wen)分(fen)析(xi)系統）穩定(ding)的(de)傳感器陣列，通過(guo)伏安(an)電(dian)化學脈(mo)沖技(ji)術(shu)激發實現原(yuan)創的(de)組合脈(mo)沖馳(chi)豫譜思想，然后(hou)經交互感應(ying)解析(xi)技(ji)術(shu)來獲取(qu)測(ce)(ce)量(liang)對(dui)象(xiang)的(de)整體(ti)信息(xi)，快(kuai)速、實時、在線實現對(dui)產品的(de)整體(ti)特征評價及若干成(cheng)分(fen)定(ding)性定(ding)量(liang)的(de)快(kuai)速檢測(ce)(ce)與分(fen)析(xi)。

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子舌（味覺指紋分(fen)析(xi)系統(tong)）伏安(an)(an)型(xing)(xing)傳(chuan)感器常使(shi)用(yong)的工作電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)為(wei)金屬裸(luo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)或(huo)修飾電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)等(deng)。基(ji)本原理是借助電(dian)(dian)(dian)(dian)(dian)(dian)(dian)化(hua)學(xue)伏安(an)(an)法的思想，將多(duo)傳(chuan)感器陣列置于待測(ce)溶液中，在工作電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上加(jia)入階躍電(dian)(dian)(dian)(dian)(dian)(dian)(dian)勢(shi)，通過檢(jian)測(ce)不同(tong)待測(ce)溶液產(chan)生極(ji)(ji)(ji)化(hua)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流大小(xiao)的不同(tong)來(lai)定性(xing)和定量分(fen)析(xi)樣(yang)品的特性(xing)。伏安(an)(an)型(xing)(xing)傳(chuan)感器所加(jia)的階躍電(dian)(dian)(dian)(dian)(dian)(dian)(dian)勢(shi)主要有循環伏安(an)(an)、常規大幅(fu)脈沖和多(duo)頻脈沖伏安(an)(an)法等(deng)。以伏安(an)(an)型(xing)(xing)傳(chuan)感器構建的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子舌系統(tong)常采用(yong)三電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)結構：工作電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)、參比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)和輔(fu)助電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。

電子舌原理簡單(dan)易(yi)懂，儀器(qi)操作簡單(dan)易(yi)學，數據處理快速(su)準確(que)，可用于多種物質如(ru)食品、藥(yao)品、農產品等(deng)物質滋味分析，質量控制，工藝優化，產品篩(shai)選，貨架期預(yu)測等(deng)。

基于此工作原理的電子舌（味覺指紋分析(xi)系統）能在科研過(guo)程中發揮良(liang)好作用。
