Cov ntsiab lus ntawm kev nkag siab

Wearable technology applications suav nrog kev saib xyuas tib neeg kev noj qab haus huv, robotics, human-machine interfacing, thiab ntau dua. Kev nce qib ntawm cov ntawv thov no tau ua rau muaj kev tshawb fawb ntxiv ntawm cov khoom siv uas tuaj yeem siv zog rau lawv tus kheej yam tsis muaj cov khoom siv ntxiv.

Wearable microgrids ntsiab lus

Cov kws tshawb fawb tab tom tshawb nrhiav yuav ua li cas cov khoom siv hnav tuaj yeem tau txais txiaj ntsig los ntawm tus kheej microgrid ntawm hws lub zog los txuas ntxiv lawv lub peev xwm. Lub microgrid hnav tau yog ib qho kev sib sau ntawm cov khoom siv hluav taws xob thiab khaws cia uas tso cai rau cov khoom siv hluav taws xob ua haujlwm ntawm nws tus kheej ntawm cov roj teeb. Tus kheej microgrid yog tswj los ntawm ib lub kaw lus rau kev hnov, pom, hloov ntaub ntawv, thiab kev tswj interface. Lub tswv yim ntawm wearable microgrid tau muab los ntawm "Island-hom" version. Qhov kev sib cais microgrid no suav nrog lub network me me ntawm lub zog tsim hluav taws xob, cov txheej txheem tswj hwm hierarchical, thiab cov khoom thauj uas tuaj yeem ua haujlwm ntawm nws tus kheej los ntawm thawj daim phiaj hluav taws xob.

Thaum tsim microgrids hnav, cov kws tshawb fawb yuav tsum xav txog lub zog ntsuas thiab hom kev thov. Qhov luaj li cas ntawm cov khoom siv hluav taws xob yuav ua raws li qhov yuav tsum tau muaj zog npaum li cas los ntawm daim ntawv thov. Piv txwv li, kev kho mob implantables yog txwv nyob rau hauv qhov loj thiab qhov chaw vim hais tias lawv xav tau cov roj teeb loj. Txawm li cas los xij, los ntawm kev siv lub zog tawm hws, implantables yuav muaj peev xwm ua kom me me thiab ntau yam.

Kev cuam tshuam

Xyoo 2022, ib pab pawg nanoengineers los ntawm University of San Diego, California, tau tsim lub "wearable microgrid" uas khaws lub zog los ntawm hws thiab txav mus los, muab lub zog rau cov khoom siv hluav taws xob me me. Cov cuab yeej muaj xws li biofuel hlwb, triboelectric generators (nanogenerators), thiab supercapacitors. Txhua qhov chaw yog hloov tau thiab tshuab-ntxuav, ua rau nws zoo tagnrho rau lub tsho. 

Cov pab pawg thawj zaug tau txheeb xyuas cov khoom siv hws-txiav tawm hauv xyoo 2013, tab sis txij li thaum cov thev naus laus zis tau loj hlob muaj zog ntxiv kom haum rau cov khoom siv hluav taws xob me me. Lub microgrid tuaj yeem khaws lub LCD (kua siv lead ua kua) lub dab teg ua haujlwm rau 30 feeb thaum khiav 10 feeb thiab 20 feeb so. Tsis zoo li triboelectric generators, uas muab hluav taws xob ua ntej tus neeg siv yuav txav tau, biofuel hlwb tau qhib los ntawm hws.

Tag nrho cov khoom yog sewn rau hauv ib lub tsho thiab txuas nrog nyias, hloov tau nyiaj ntawm cov xov hlau luam tawm ntawm cov ntaub thiab coated rau rwb thaiv tsev nrog cov khoom tsis muaj dej. Yog tias lub tsho tsis tau ntxuav nrog xab npum, cov khoom yuav tsis tawg los ntawm kev rov khoov, folding, crumpling, lossis soaking hauv dej.

Cov hlwb biofuel nyob hauv lub tsho thiab sau lub zog los ntawm hws. Lub caij no, lub tshuab hluav taws xob triboelectric muab tso rau ze ntawm lub duav thiab sab ntawm lub cev kom hloov mus rau hauv hluav taws xob. Ob qho khoom siv no ntes lub zog thaum tus neeg hnav taug kev lossis khiav, tom qab ntawd cov supercapacitors sab nraud ntawm lub tsho cia lub zog ib ntus los muab lub zog rau cov khoom siv hluav taws xob me me. Cov kws tshawb fawb xav paub ntxiv txog kev sim cov qauv tsim yav tom ntej los tsim lub zog thaum tus neeg tsis ua haujlwm lossis nyob ruaj khov, xws li zaum hauv chaw ua haujlwm.

Kev siv ntawm wearable microgrids

Qee qhov kev siv ntawm wearable microgrids yuav suav nrog: 

• Smartwatches thiab Bluetooth earphones raug them thaum lub sijhawm ua haujlwm, khiav, lossis caij tsheb kauj vab.
• Cov khoom siv kho mob xws li biochips tau siv los ntawm tus neeg hnav lub zog lossis lub cev kub.
• Wireless them khaub ncaws khaws cia lub zog tom qab hnav. Qhov kev txhim kho no yuav tso cai rau cov khaub ncaws xa hluav taws xob mus rau tus kheej cov khoom siv hluav taws xob xws li smartphones thiab ntsiav tshuaj.
• Txo cov pa roj carbon emissions thiab txo lub zog noj raws li tib neeg tuaj yeem them lawv cov khoom siv ib txhij thaum siv lawv.
• Kev tshawb fawb ntxiv txog lwm yam muaj peev xwm ntawm cov microgrids hnav, xws li khau, khaub ncaws, thiab lwm yam khoom siv xws li wristbands.

Cov lus nug los xav txog

• Yuav ua li cas lwm tus tuaj yeem hnav lub zog siv tau los txhim kho thev naus laus zis thiab kev siv?
• Cov cuab yeej zoo li no tuaj yeem pab koj li cas hauv koj txoj haujlwm thiab kev ua haujlwm txhua hnub?
