Txog cov teebmeem thiab kev ua haujlwm ntawm cov khoom Electrode

Hluav taws xobCov khoom lag luam yog cov khoom tseem ceeb ntawm cov tshuaj electrochemical zoo thiab cov kev daws teeb meem zog, thiab siv dav hauv kev khaws cia zog (xws li roj teeb, supercapacitors), cov khoom siv kho mob (ECG / EEG saib xyuas) thiab kev saib xyuas ib puag ncig (kev tshuaj xyuas dej zoo, kev tshawb pom cov pa phem). Nws cov conductivity siab, kev ruaj khov thiab kev ua kom zoo dua ntawm cov khoom siv (carbon, hlau, nanostructure, thiab lwm yam) ua kom muaj kev ua haujlwm ruaj khov, pab txhim kho lub zog rov ua dua tshiab, tsheb fais fab thiab tshuaj kho mob, thiab txhawb kev tsim kho tshiab ntawm kev siv tshuab.

Cov khoom siv electrode tau dhau los ua cov cuab yeej tseem ceeb hauv ntau yam lag luam vim lawv cov haujlwm tshwj xeeb thiab cov ntawv thov nplua nuj. Cov khoom no yog tsim los pab txhawb ntau yam txheej txheem los ntawm cov tshuaj electrochemical mus rau cov kev daws teeb meem khaws cia lub zog. Qhov zoo ntawm cov khoom siv electrode tsis yog tsuas yog nyob rau hauv lawv cov kev ua haujlwm zoo, tab sis kuj nyob rau hauv lawv lub peev xwm los hloov kho rau ntau qhov chaw thiab kev xav tau.

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov khoom Electrode yog lawv qhov kev ua tau zoo tshaj plaws hauv kev siv electrochemical. Cov electrodes no tau tsim los kom muaj kev coj ua siab, kev ruaj khov thiab kev ua haujlwm ntev, uas yog qhov tseem ceeb rau cov txheej txheem xws li electrolysis, kev ua haujlwm roj teeb thiab kev siv roj teeb. Cov ntaub ntawv siv hauv cov khoom electrode, xws li carbon, hlau thiab conductive polymers, tau xaiv los ua tib zoo kom tiv taus cov xwm txheej hnyav thiab tswj kev ua tau zoo tshaj plaws. Qhov no ua kom ntseeg tau tias cov lag luam uas vam khom cov txheej txheem electrochemical tuaj yeem ua tiav cov txiaj ntsig zoo sib xws, yog li ua rau muaj kev tsim khoom ntau ntxiv thiab txo cov nqi khiav lag luam.

Cov khoom siv hluav taws xob siv rau ntau yam xws li lub zog, kev kho mob thiab kev saib xyuas ib puag ncig. Piv txwv li, hauv kev lag luam hluav taws xob, lawv ua lub luag haujlwm tseem ceeb hauv kev tsim cov roj teeb siab heev thiab cov supercapacitors, uas yog qhov tseem ceeb rau kev khaws cia lub zog rov ua dua tshiab thiab thev naus laus zis tsheb fais fab. Hauv kev kho mob, cov hluav taws xob siv rau hauv cov khoom siv kho mob los saib xyuas thiab kuaj mob xws li electrocardiograms (ECG) thiab electroencephalograms (EEG). Tsis tas li ntawd, hauv kev saib xyuas ib puag ncig, cov hluav taws xob siv rau hauv cov sensors los ntes cov pa phem thiab ntsuas qhov zoo ntawm dej, pab txhawb kev coj ua kom ruaj khov thiab kev nyab xeeb rau kev noj qab haus huv pej xeem.

Cov khoom siv electrode ua ntau tshaj li tsuas yog ua hluav taws xob xwb; lawv kuj tsim los txhim kho kev ua haujlwm ntawm ntau yam txheej txheem. Hauv cov hlwb electrochemical, piv txwv li, kev tsim qauv thiab cov khoom siv ntawm cov electrodes tuaj yeem cuam tshuam rau qhov kev hloov pauv kinetics, ua rau kev hloov pauv hluav taws xob sai dua thiab ua haujlwm tau zoo dua. Kev nce qib hauv cov thev naus laus zis electrode, xws li kev txhim kho cov electrodes nanostructured, txhim kho kev ua haujlwm electrode ntxiv los ntawm kev nce thaj chaw thiab kev ua haujlwm. Qhov kev tsim kho tshiab no tsis yog tsuas yog txhim kho kev ua haujlwm ntawm cov ntawv thov uas twb muaj lawm, tab sis kuj qhib cov hauv kev tshiab rau cov thev naus laus zis yav tom ntej.

Hluav taws xobCov khoom lag luam yog cov khoom tseem ceeb hauv ntau daim ntawv thov thoob plaws ntau yam lag luam. Lawv cov txiaj ntsig xws li kev ua tau zoo, kev ruaj khov thiab kev hloov pauv ua rau lawv tseem ceeb rau kev txhim kho kev ua haujlwm ntawm cov txheej txheem electrochemical. Raws li thev naus laus zis txuas ntxiv txhim kho, lub luag haujlwm ntawm cov khoom electrode yuav txuas ntxiv nthuav dav, paving txoj hauv kev rau cov kev daws teeb meem tshiab rau cov teeb meem hauv kev khaws cia lub zog, kev kuaj mob thiab kev ruaj khov ib puag ncig. Los ntawm kev siv tshuab electrode siab heev, kev lag luam thoob plaws ntau yam lag luam tsis tsuas yog tuaj yeem txhim kho kev ua haujlwm zoo, tab sis kuj pab txhawb rau yav tom ntej ruaj khov thiab thev naus laus zis siab dua.
