Zomwe zimapangidwazo zimagwirizana ndi khungu lamagetsi lopumira, losawonongeka, loletsa antibacterial komanso lodziyendetsa nokha lokhala ndi mphamvu yamagetsi ya nanofiber yotengera nanogenerator.

Monga chiwalo chachikulu kwambiri cha thupi la munthu, khungu la munthu silingokhala ndi ntchito zoyambira zoteteza, kubisala komanso kupuma, komanso ndi dongosolo lofunikira la somatosensory polumikizana ndi kulumikizana pakati pa anthu ndi zinthu zakuthupi. M'zaka zaposachedwapa, chitukuko cha bionic pakompyuta khungu anadzutsa chidwi kwambiri ofufuza, ndipo ali osiyanasiyana ntchito pa wearable munthu kuwunika thanzi, wanzeru prosthesis ndi robotics, anthu-kompyuta mogwirizana ndi nzeru yokumba.

Kutengera njira zosiyanasiyana zowonera thupi, khungu lamagetsi limatha kugawidwa mumitundu ya piezoresistive, capacitive, piezoelectric ndi triboelectric. Khungu lamagetsi limazindikira ndikuwunika zinthu zosiyanasiyana zachilengedwe, kuphatikiza kutentha, chinyezi, kupanikizika, kugwedezeka ndi kukhudza, ndikuzisintha kukhala zenizeni zenizeni komanso zowonera zamagetsi. Friction mphamvu ndi mtundu wogwiritsa ntchito kukhudzana kwamagetsi ndi mphamvu yolumikizira ya electrostatic induction, mphamvu yamakina yamtengo wapatali imatha kusinthidwa kukhala mphamvu yamagetsi yofikira kuukadaulo watsopano wamagetsi, mtengo wotsika, kapangidwe kosavuta, kugwiritsa ntchito kosavuta, kusankha kwazinthu, kutembenuka kwakukulu, etc. M'munda wa wearable mphamvu gwero ndi kachipangizo magetsi ali yotakata ntchito chiyembekezo, ndi kusankha abwino mphamvu ufulu wodziimira pakhungu pakompyuta.

Kusinthasintha, kuwonjezereka, kukhudzika, kusinthasintha ndi kukhazikika kwa makina ndi njira zofufuzira zodziwika bwino pakhungu lamagetsi pakali pano, zomwe ndizosavuta kuzizindikira. M'zaka zaposachedwa, pofuna kupititsa patsogolo machitidwe a khungu lamagetsi, ntchito zapadera za khungu lamagetsi, monga kukonzanso, kudzichiritsa, kukumbukira mawonekedwe, electroluminescence ndi luminescence yamakina, zaphunziridwa pang'onopang'ono. Ngakhale kukhathamiritsa kosalekeza ndi kusintha kwa zinthu zomwe zili pamwambazi, chitonthozo, chitetezo ndi chitetezo cha chilengedwe cha khungu lamagetsi zakhala zimanyalanyazidwa, zomwe zimalepheretsa kwambiri kugwiritsa ntchito khungu lamagetsi. Chifukwa chake, khungu lamagetsi lokhala ndi chitonthozo choyenera komanso lothandiza liyenera kukhala lopumira, lopanda biodegradable komanso antibacterial. Kuthekera kwa mpweya ndi ntchito yofunika kwambiri yosinthira kutentha ndi chinyezi ndikuzindikira kusinthana kwa mpweya pakati pa thupi la munthu ndi chilengedwe chakunja. Komabe, khungu lamagetsi lapamwamba kwambiri limagwiritsira ntchito ma nembanemba ngati maelekitirodi kapena magawo, zomwe zingayambitse kuyabwa pakhungu komanso kutupa ndi kuyabwa. Kuphatikiza apo, kukhudzana kwanthawi yayitali pakati pa khungu la e-khungu ndi khungu la munthu ndi njira yabwino yopangira kukula kwa tizilombo tating'onoting'ono, kotero kuti antibacterial properties ndizofunikira kuti khungu la e-khungu lilepheretse kukula kwa bakiteriya ndikuletsa matenda a bakiteriya. Kuphatikiza apo, zida zambiri sizimatayidwa, kumapeto kwa moyo wawo wothandiza, zitha kukhala zinyalala za e-zinyalala, kapena kuvulaza thupi la munthu kapena kuwononga chilengedwe.

Posachedwapa, gulu lofufuza la Beijing Institute of Nanometer Energy and Systems, Chinese Academy of Sciences linapanga khungu lamagetsi lopumira, losawonongeka, loletsa antibacterial komanso lodziyendetsa pawokha lokhala ndi nanofiber lokhala ndi mikangano ya nanogenerator, yomwe idazindikira kusonkhanitsa mphamvu zamakina komanso kudzimva pawokha. physiology ya thupi laumunthu ndi zizindikiro zoyenda pamodzi. Ndi poly lactic acid/glycolic acid copolymer (PLGA) ndi polyvinyl mowa (PVA) nanofibers nembanemba motero monga electrification wosanjikiza ndi gawo lapansi ndi siliva nanowires (AgNW) monga mkhalapakati, anapanga ndi Mipikisano zigawo staggered nanofibers maukonde ndi ambiri atatu. -mawonekedwe owoneka bwino a mabowo ang'onoang'ono-nano otengera mphamvu yakukangana kwapakhungu, ikhale yothandiza pakhungu la munthu komanso malo akunja otengera kutentha. Panthawi imodzimodziyo, khungu lamagetsi lili ndi katundu wabwino kwambiri wa antibacterial, limatha kulepheretsa kukula kwa Escherichia coli ndi Staphylococcus aureus, ndikuletsa matenda a bakiteriya. Posintha kukula ndi kufanana kwa biodegradable PLGA ndi PVA, kuwonongeka kwa khungu lamagetsi kumatha kusinthidwa kukhala masiku angapo mpaka milungu ingapo. Kuphatikiza apo, ndi ntchito yayikulu yotulutsa 130 mW / m2 komanso mphamvu yakuyankha kwa voltage ya 0.011 kPA-1, khungu lamagetsi limatha kuzindikira zenizeni zenizeni zomwe sizimawononga mphamvu zowunikira ma siginecha (monga ma microexpressions, kugunda, kupuma). ndi maitanidwe) ndi mayendedwe olowa (monga ma knuckles, elbows, mawondo ndi akakolo) a thupi la munthu. Ntchitoyi imapereka njira yofufuzira yomwe sinachitikepo kuti pakhale khungu lamagetsi logwira ntchito zambiri. Zotsatira za "A breathable, biodegradable, antibacterial, and self-powered electronics skin - based on all - nanofiber triboelectric nanogenerators" mutu, lofalitsidwa mu Science Advances.

Mapangidwe apangidwe ndi mawonekedwe amtundu wamtundu wamtundu wamagetsi wa nanofiber kutengera mikangano nanogenerator

Makhalidwe amphamvu, mpweya permeability, ndi magetsi linanena bungwe katundu

Makhalidwe a antimicrobial ndi biodegradable properties

Zizindikiro za kachitidwe ka thupi komanso kuwunika kolumikizana
