Suav Academy ntawm Sciences tau tsim cov kev siab dav, siab-stretchability, tawv zoo li nano-txhuam generators
Nyob rau hauv xyoo tas los no, nrog rau ntau yam ntawm cov khoom siv hauv kev lag luam xws li cov hluav taws xob transistors / integrated circuits, stretchable optoelectronic, foldable lus, thiab hluav taws xob hauv daim tawv nqaij, flexible / stretchable electronic products tau tsim sai heev.
Cov khoom muaj nqis ntau dua ntawm lawv cov khoom siv hluav taws xob thiab yuav tsum muaj kev txav txim siab thiab kev ncab. Txawm li cas los xij, ob peb lub zog muaj peev xwm ua tau yooj yim, kom pom tseeb, thiab ncab ntawm tib lub sijhawm. Tsis tas li ntawd, kev loj hlob ntawm kev lag luam hauv hluav taws xob thiab implantable hluav taws xob cov khoom yuav tsum kom lawv cov khoom siv hluav taws xob ntxiv muaj zoo biocompatibility ntxiv rau kev ywj pheej thiab kev ncab.
Cov pa hluav taws xob electromagnetic generators yog qhov nyuaj rau qhov ncab, thiab tsis ntev los no cov kev sib txhuam los ntawm kev sib txhuam nanogenerator (TENG) tuaj yeem ua raws li cov kev cai ntawm cov khoom siv hluav taws xob. Tsis ntev los no, cov qauv kev sib tw nanogenerators muaj feem ntau tau ua los ntawm cov qauv siv hluav taws xob uas siv cov qauv siv hluav taws xob xws li carbon nanotubes, graphene, thiab nyiaj nanowires. Txawm li cas los xij, cov ntaub ntawv zoo li no tsis muaj kev txwv thiab tsis yooj yim los ua kom tau siab. Hauv kev sib piv, hydrogels yog tsim los ntawm ib lub network hydrophilic polymer thiab ib qho kev sib tov los yog aqueous ionic tov tau ib txhij ncav ua haujlwm, npliag nplaum, biocompatibility, thiab ncab, ua rau lawv zoo rau kev tsim kev yoojyim kev sib tw nanogenerators.
Raws li kev sib koom tes ntawm tus xibfwb Wang Zhonglin thiab tus neeg tshawb nrhiav Hu Weiguo ntawm lub Tsev Kawm Ntawv Nano-Energy thiab Systems, Suav Academy ntawm Sciences, cov neeg tshawb xyuas ntawm Puab Nruab Nrab ntawm Nano zog thiab Systems, Pu Xiong, nrog cov elastomer thiab ion hydrogel los tsim lub npe tshiab Cov tawv nqaij zoo li nano-txhuam generator (STENG), uas thawj zaug tau txais kev kaj siab (nruab nrab lub teeb kis las, pom lub teeb pom kev 96.2%) thiab ultra-high stretchability (uniaxial strain, 1160%), thaum ua kom muaj zog Sau, tactile xaav thiab lwm yam haujlwm. Cov hauj lwm no muab lub tswv yim tshiab rau txoj kev kawm txog cov cuab yeej los ntawm kev siv zog, thiab cov hluav taws xob uas yooj yim, thiab cov kev tshwm sim tau luam tawm hauv ScienceAdvances (DOI: 10.1126 / sciadv.1700015).
Qhov no STENG muaj peev xwm ua kom muaj qhov qhib hluav taws xob ntawm qhov siab txog 145 volts nrog lub zog ceev ceev ntawm 35 mW / m2. STENG muaj kev lagluam sab nrauv. Vim tias cov khoom tsim los ntawm cov pa roj biocompatible, nws tuaj yeem ncaj qha mus rau daim tawv nqaij ntawm tib neeg lub cev thiab tsav ntau yam khoom siv hluav taws xob xws li LEDs thiab cov watches hauv tshuab hluav taws xob. Txoj kev tshawb no ua ntej npaj siab rau STENG nrog ultra-high stretchability thiab transparency. Vim nws cov kev kaj siab, nws tsis cuam tshuam nrog kev sib kis ntawm cov ntaub ntawv kho qhov muag, thiab tib lub sij hawm txuas lub zog harvesting thiab kov kev xav. Yog li ntawd, nyob rau hauv ntse daim tawv ntse, self-driven software neeg hlau, Muaj peev xwm siv cov ntaub ntawv yooj ywm thiab wearable electronics.
