Cov cuab yeej cuab tam tau yog cov roj tawg, cia siab rau kev coj ua Gel, thiab muaj kev cuam tshuam rau kev cuam tshuam. Rau lub hlwb - lub computer interface (BCI) thev naus laus zis los ua ib feem ntawm lub neej txhua hnub, muaj kev txhim kho yuav tsum pib thaum pib. Tsis ntev los no, ib pab neeg coj los ntawm kev tshawb fawb liu tau khiav thiab cov xibfwb Gao XiaRed electrishing institishing innections condition tab sis kuj muaj cov txiaj ntsig zoo tab sis kuj muaj cov txiaj ntsig Ntawm ua gel - Dawb, hnav, thiab sib haum heev. Qhov tshiab ntawm electrode txoj kev rau BCI cov cuab yeej ua kom dhau los ua qhov chaw.
Ⅰ. Smarter "hlwb thaj"
Cov khoom lag luam Electroencefharaphy (EEG) feem ntau siv gel - Raws li cov hluav taws xob ntub. Thaum lawv muaj cov cim ruaj khov zoo, lawv tuaj yeem ua rau kev siv, tuaj yeem ua rau cov tawv nqaij khaus, thiab tuaj yeem raug kev cuam tshuam rau kev cuam tshuam. Nyob rau hauv xyoo tas los, cov hluav taws xob qhuav tau tshwm sim ua lwm txoj, tab sis ntsuas ntawm kev ua kom zoo, teeb liab kev sib tw hauv cov ntaub ntawv txuj ci thiab neuroengineering.
Pab neeg tshawb fawb no tau siv mxene (ib hom ntawm ob {{0} nws cov qauv siv roj ntsha kom tsim qauv hluav taws xob qhuav xwb 1 square millimeter. Mxene tau tsis ntev los no tua tau dav dav rau nws cov kev ua tau zoo heev, hloov tau yooj yim, thiab biocompatibility. Lub microneedle array ua rau electrode rau "yooj yim nkag mus rau sab nrauv sab nrauv, thiab kev ua kom muaj zog, siab}} Cov suab nrov piv rau EEG paib. Tus qauv no tsis suav nrog kev sib cuag nrog electrode thiab taub hau, tab sis kuj muaj qhov zoo xws li kev tawm tsam mus rau kev tawm tsam, hws, thiab rov ua dua.
Ⅱ. Kev ua thiab kuaj: Tsis yog lub teeb yuag, tab sis kuj tau tshaj MRI thiab siab-} ceev rail thov.
Txhawm rau txheeb xyuas cov electrode cov kev ua tau zoo, cov kws tshawb nrhiav tau ua cov khoom lag luam uas tau sim ua ntej, suav nrog cov khoom siv, suav nrog kev ua tau zoo, thiab MRI sib txawv.
Ua ntej, nyob rau hauv electrode fabrication, cov kws tshawb fawb ua haujlwm siv micromolding thiab hydrogel cov cab kuj ua kom cov microneedle arrier cia li tswj tau cov kev puas tsuaj zoo nkauj. Cov nplaim tau kho nrog cov khoom mxene, tso cai rau kev tswj hwm tuab ntawm cov txheej txheem condentive, ua tiav cov qauv kev ruaj ntseg thiab cov teeb liab siab uas muaj peev xwm ntes tau.
Thaum lub sijhawm ntsuas cov teeb liab, cov pab pawg tau thov cov electrode rau ib lub hlwb nquag paradigm: khov kho- Lub Xeev Visuals (SSVEP). SSVEP tam sim no yog ib qho ntawm cov khoom siv ruaj khov thiab raug rau tsis} {}}} {}}}}}}}}}} illely Cov txiaj ntsig kev sim ua tau pom tias Microhedle electrode tau ua tiav qhov tseeb ntawm SSRP teeb liab nrhiav tau ntau dua hauv ib puag ncig ib puag ncig thiab nrog kev txav mustus tsawg.
Feem ntau, cov pab pawg tshawb fawb kuj tau ntsuas lub tshuab hluav taws xob nrog kev sib nqus lossis cov khoom siv hluav taws xob muaj zog, pom zoo rau kev sib nqus ntawm cov khoom sib nqus Tsis tas li ntawd, kev soj ntsuam biocompatibility tau ua rau pom tias lub sijhawm ntev dhau los tsis ua rau cov mob sab nrauv lossis cov tawv nqaij kom haum, ua rau kev soj ntsuam txhua hnub lossis txuas ntxiv.
Ⅲ. Pib tshiab rau "xoom -} sensor" BCIS
Qhov tseem ceeb tshaj plaws ntawm cov kev tshawb fawb no nyob hauv nws qhov kev sib tawg hauv kev ua lag luam - tawm ntawm kev nplij siab thiab kev ua tau zoo hauv cov khoom siv EEG. Los ntawm kev sib txuas ua ke ntawm cov qauv mxene nrog cov qauv hluav taws xob ntawm cov qauv micre}}} Nrhiav tau cov khoom siv BCI rau qhov "hnav zoo".
Nyob rau yav tom ntej, peb tau hais txog cov microSedle hluav taws xob yuav muab ua ke nrog cov ntsaws kev sib txuas lus, thiab} Lub neej ua si rau lub neej txhua hnub. Tsis tas li ntawd, nws kuj tseem yuav ua cov ntawv thov kev kho mob dav dav, suav nrog cov neurorehabilitation, ceeb toom mob hnoos qeev, thiab kev txhawb nqa tsaug zog. Rau lub hlwb - photterface interface kev lag luam, qhov no txhais tau tias "kawg mais" los ntawm kev kuaj mob rau lub khw ua lag luam.
