Muaj feem xyuam nrog roj teeb them: roj teeb them rau cov khoom siv ntse hnav

Txog kev them nyiaj: them lub roj teeb uas siv tau

Cov khoom siv Wearable tau dhau los ua cov thev naus laus zis nrov, tab sis roj teeb lub neej kuj tau dhau los ua qhov teeb meem rau ntau tus kws tshawb fawb thiab cov chaw tsim khoom.

1. Hloov hluav taws xob zoo li qub rau hauv hluav taws xob siv tau

Tsis ntev los no, ib pab neeg los ntawm National University of Singapore (National University of Singapore) tau tsim cov khoom siv tau yooj yim thiab compact uas tuaj yeem hloov hluav taws xob tam sim ntawd mus rau hauv lub zog siv tau. Ib qho kawg ntawm lub cuab yeej kov lub ntsej muag ntawm daim tawv nqaij, thiab lwm qhov kawg yog npog nrog cov yeeb yaj kiab kub-silicon. Ua ke nrog cov cuab yeej, muaj cov kab silicone roj hmab ntawm ob qho kawg, uas tso cai rau lub zog ntau dua thiab sib cuag ntawm daim tawv nqaij ntau dua.

Pab pawg tau nthuav tawm lawv cov txiaj ntsig ntawm 2015 IEEEMEMS lub rooj sib tham thiab tau ua pov thawj tias tam sim no tawg tuaj yeem siv zog rau qee yam khoom siv. Los ntawm kev txhim kho cov cuab yeej ntawm cov ncauj lus ntawm caj npab thiab caj pas, lawv tuaj yeem tsim 7.3V tam sim no los ntawm kev tuav lawv lub nrig thiab 7.5V los ntawm kev hais lus. Daim ntawv tso zis tso quav tsis tu ncua, thiab qhov siab tshaj plaws yog 90V, uas tuaj yeem ncaj qha mus rau lub teeb ci LED. Pab neeg no npaj tsim cov roj teeb loj dua yav tom ntej kom lawv siv tau ntau lub zog tsim los ntawm tib neeg cov tawv nqaij sib txhuam.

Ntxiv nrog rau lub zog ntawm lub roj teeb tiv thaiv no, muaj ntau txoj hauv kev los tham txog nws hauv ntiaj teb. Piv txwv li, hom tattoo tshiab tuaj yeem tig tib neeg tawm hws mus rau hauv hluav taws xob, lossis tig peb lub puab tsaig rau hauv lub tshuab hluav taws xob nrog lub pob ntseg tshwj xeeb. Nws zoo nkaus li tias muaj qee txoj hauv kev tshwj xeeb los tswj lub zog ntawm cov khoom siv yav tom ntej.

2. Tshiab tattoo: hws hloov mus rau hauv hluav taws xob

Thaum Lub Yim Hli 16, Joseph wang (JosephWang), tus kws tshawb fawb ntawm University of California, San Diego, tau tsim lub tattoo ib ntus ntse uas tuaj yeem tsim hluav taws xob los ntawm hws thiab ib hnub fais fab xov tooj ntawm tes thiab lwm yam khoom siv siv tau.

Lub tattoo yuav lo rau koj cov tawv nqaij, ntsuas cov tshuaj lactic acid hauv koj lub hws, thiab tom qab ntawd siv cov lactic acid los ua cov roj micro. Thaum peb cob qhia kom qaug zog, cov leeg nqaij feem ntau hnov ​​​​qhov kub hnyiab, uas cuam tshuam nrog kev sib txuam ntawm lactic acid. Rau cov leeg, lactic acid yog pov tseg, nws yog qhov kawg ntawm nws tus kheej.

Cov kws kho mob qoj ib ce tam sim no tuaj yeem ntsuas cov qib lactic acid hauv cov leeg lossis ntshav. Thaum lactic acid raug tso tawm los ntawm hws, qhov kev paub tshiab tau yug los. Wang tau tsim ib lub tattoo ntse uas siv lub sensor los rho cov electrons los ntawm lactic acid los ua rau hluav taws xob tam sim no. Wang kwv yees tias 70 microwatts ntawm hluav taws xob tuaj yeem tsim tawm ib square centimeter ntawm daim tawv nqaij. Cov kws tshawb fawb tau ntxiv cov roj teeb rau lub lactic acid sensor los ntes thiab khaws cov hluav taws xob tam sim no, thiab tom qab ntawd tsim qhov lawv hu ua biofuel cell.

Txawm hais tias koj tsav tsheb lossis taug kev, koj hws ntau dua, lactic acid ntau dua, uas txhais tau hais tias koj lub roj teeb tuaj yeem khaws ntau lub zog. Tam sim no, xws li tattoos tsuas tuaj yeem tsim lub zog me me xwb, tab sis cov kws tshawb fawb cia siab tias lub xov tooj ntawm tes biofuel no yuav muaj ib hnub tsim kom muaj zog txaus rau lub zog ntse saib, ntsuas lub plawv dhia lossis lub xov tooj ntse.

Motorola kuj tau tsim lub tattoo ib ntus uas tuaj yeem siv los qhib lub xov tooj. Tej zaum nws yog qhov yuav tsum muaj khoom siv ntxiv rau koj lub xov tooj, lossis koj tsuas yog xav tau tus cwj mem me me xwb.

Guangdong lithium roj teeb tsis yog tsuas yog haum rau kev siv loj xws li cov chaw tsim hluav taws xob thiab cov teeb pom kev zoo. Peb yuav pom cov hnub ci hluav taws xob me me hluav taws xob hnav cov khoom siv. Lub hnub ci watches tsis muaj roj teeb muaj nyob rau ntau xyoo. EnergyBioNIcs tsis ntev los no tau tsim lub hnub ci saib uas tuaj yeem ua tau raws li nws cov kev xav tau thiab cov kev xav tau ntawm lwm yam khoom siv.

Ib qho teeb meem nrog kev siv lub hnub ci hlwb hauv cov khoom siv hnav yog tias cov cuab yeej xav tau lub teeb los tsim hluav taws xob. Yog tias lub teeb raug thaiv, xws li hauv qab lub tes tsho, nws tsis tuaj yeem tsim hluav taws xob. Tab sis los ntawm lwm qhov kev xav, nws kuj ua rau lub hnub ci lub hnub ci yog qhov kev xaiv zoo rau cov khaub ncaws ntse, vim tias lub roj teeb hloov tau txawm tias yuav sewn ncaj qha rau ntawm cov ntaub.

Cov hnub ci hnub ci niaj hnub muab lub hnub ci zog dua li cov teeb pom kev sab hauv tsev. Txhawm rau daws qhov teeb meem no, tib neeg tab tom tsim cov ntaub ntawv tshiab rau kev tsim hluav taws xob sab hauv tsev, thiab kev ua tau zoo kuj tseem txhim kho.

4. Thermoelectric teeb

thermoelectric sau siv lub hauv paus ntsiab lus ntawm lub cev hu ua Seebeck effect los hloov cov cua sov rau hauv hluav taws xob. Perot cov ntsiab lus tau ua ke nrog ib khub ntawm cov khoom siv hluav taws xob tshwj xeeb, thiab tam sim no tuaj yeem tsim los ntawm kev qhia qhov kub thiab txias sib txawv.

Rau cov khoom siv hnav, tib neeg lub cev tuaj yeem siv los ua qhov kub kawg, ib puag ncig tuaj yeem siv los ua qhov txias kawg, thiab tib neeg lub cev tsis tu ncua emits cua sov. Lub zog cuam tshuam yog nyob ntawm tus nqi delta ntawm qhov kub thiab txias. Perot caij tuaj yeem sau tau ntau lub zog, thiab nws muaj peev xwm siv tau rau hauv cov khoom siv uas nyob ze rau ntawm daim tawv nqaij thiab xav tau ntau lub zog. Ib qho txiaj ntsig zoo ntawm lub voj voog thermoelectric yog tias nws muaj lub zog tas li, txawm tias nws nyob hauv tsev lossis sab nraum zoov, nruab hnub lossis hmo ntuj.
