Asayansi apanga achipinda chojambulira opanda zingweyomwe imatha mphamvu laputopu iliyonse, piritsi kapena foni yam'manja kudzera mumlengalenga popanda kufunikira kwa mapulagi kapena zingwe.
Gulu la University of Tokyo linanena kuti njira yatsopanoyi ikuphatikizapo kupanga maginito mtunda wautali popanda kupanga magetsi omwe angakhale ovulaza kwa aliyense kapena nyama m'chipindamo.
Dongosolo, lomwe layesedwa m'chipinda koma likadali laling'ono, limatha kupereka mphamvu mpaka 50 Watts popanda kupitilira malangizo apano akuwonetsa kuti anthu amakumana ndi maginito, olemba kafukufuku adafotokoza.
Itha kugwiritsidwa ntchito kulipiritsa chipangizo chilichonse chokhala ndi koyilo mkati, chofanana ndi kachitidwe kamene kamagwiritsidwa ntchito ndi mapadi opangira opanda zingwe - koma opanda pad yolipiritsa.
Kuphatikiza pa kuchotsa mitolo ya zingwe zolipiritsa pamadesiki, zitha kulola kuti zida zambiri zizichitika zokha popanda kufunikira kwa madoko, mapulagi kapena zingwe, gululo lidatero.
Gululo linanena kuti dongosolo lamakono limaphatikizapo chitsulo cha maginito pakati pa chipindacho kuti chilole mphamvu ya maginito "kufika pa ngodya iliyonse", koma imagwira ntchito popanda izo, kunyengerera kukhala "malo akufa" kumene kulipiritsa opanda waya sikutheka.
Ofufuzawo sananene kuti teknolojiyi idzawononga ndalama zingati chifukwa idakali kumayambiriro kwa chitukuko komanso "zaka zambiri" kuti zisakhalepo kwa anthu.
Komabe, ngati kuli kotheka kubwezeretsanso nyumba yomwe ilipo kapena kuphatikiza nyumba yatsopano, yokhala ndi kapena popanda mzati wapakati.
Tekinolojeyi idzalola chipangizo chilichonse chamagetsi - monga foni, fani kapena nyali - kuti chiyimitsidwe popanda kufunikira kwa zingwe, ndipo monga momwe tawonera m'chipinda chino chomwe chinapangidwa ndi yunivesite ya Tokyo, chimatsimikizira kuti chimagwira ntchito.Zosaoneka ndizopakati. pole, zomwe zimathandizira kukulitsa kukula kwa maginito
Dongosololi limaphatikizapo positi pakatikati pachipindacho kuti "adzaze mipata yomwe sinaphimbidwe ndi ma capacitors apakhoma," koma olembawo akuti ikadagwirabe ntchito popanda positi, monga momwe zasonyezedwera, koma zitha kukhala malo akufa pomwe kulipiritsa sikungachitike. ntchito
Ma capacitor okhala ndi lumped, opangidwa kuti alekanitse dongosolo lamatenthedwe, amayikidwa pakhoma la khoma lililonse kuzungulira chipindacho.
Izi zimachepetsa chiopsezo cha anthu ndi nyama zomwe zili mumlengalenga, chifukwa minda yamagetsi imatha kutentha nyama yachilengedwe.
A chapakati conductive elekitirodi anaika mu chipinda kupanga zozungulira maginito mphamvu.
Popeza mphamvu ya maginito imakhala yozungulira mwachisawawa, imatha kudzaza mipata iliyonse m'chipinda chomwe sichikuphimbidwa ndi ma capacitors a khoma.
Zipangizo monga mafoni a m'manja ndi laputopu zili ndi zozungulira mkati zomwe zimatha kulipitsidwa pogwiritsa ntchito maginito.
Dongosolo limatha kupereka ma Watts 50 amphamvu popanda chiopsezo kwa anthu kapena nyama m'chipindamo.
Ntchito zina zimaphatikizapo zida zing'onozing'ono zamagetsi m'mabokosi a zida, kapena zokulirapo zomwe zimatha kulola mbewu zonse kugwira ntchito popanda zingwe.
"Izi zimathandizira kwambiri mphamvu zamakompyuta padziko lonse lapansi - mutha kuyika kompyuta yanu kulikonse osadandaula za kulipiritsa kapena plug," adatero wolemba nawo kafukufuku Alanson Sample waku University of Michigan.
Palinso ntchito zachipatala, malinga ndi Zitsanzo, yemwe adati ma implants amtima pakali pano amafunikira waya kuchokera papampu kuti udutse m'thupi ndi kulowa mu socket.
"Izi zitha kuthetsa vutoli," akutero olembawo, ndikuwonjezera kuti zitha kuchepetsa chiopsezo chotenga matenda mwa kuchotseratu mawaya, "kuchepetsa chiopsezo chotenga matenda ndikuwongolera moyo wa wodwalayo."
Kulipiritsa opanda zingwe kwatsimikizira zotsutsana, ndi kafukufuku waposachedwa wapeza kuti mtundu wa maginito ndi ma coil omwe amagwiritsidwa ntchito pazinthu zina za Apple amatha kutseka ma pacemaker ndi zida zofananira.
"Kafukufuku wathu wokhudza ma static cavity resonances sagwiritsa ntchito maginito osatha chifukwa chake sakhala ndi nkhawa zokhudzana ndi thanzi ndi chitetezo," adatero.
"M'malo mwake, timagwiritsa ntchito maginito otsika kwambiri kuti titumizire magetsi opanda zingwe, ndipo mawonekedwe ndi mawonekedwe a ma resonator amatipatsa mwayi wowongolera ndikuwongolera magawowa.
"Timalimbikitsidwa kuti kuwunika kwathu koyambirira kwachitetezo kunawonetsa kuti mphamvu zothandiza zitha kusamutsidwa mosamala komanso moyenera.Tipitiliza kufufuza ndi kupanga ukadaulo uwu kuti ukwaniritse kapena kupitilira miyezo yonse yotetezedwa.
Kuti awonetse dongosolo latsopanoli, adayika zida zapadera zolipiritsa opanda zingwe mu "chipinda choyesera" cha 10-foot-by-10-foot aluminium.
Kenako amazigwiritsa ntchito popangira magetsi, mafani ndi mafoni am'manja, kujambula magetsi kuchokera kulikonse m'chipindacho, mosasamala kanthu komwe mipando kapena anthu ayikidwa.
Ofufuzawo ati dongosololi ndikusintha kwakukulu poyerekeza ndi zomwe zidayesa kale kuyitanitsa opanda zingwe, zomwe zidagwiritsa ntchito ma radiation owopsa a microwave kapena zimafuna kuyika chipangizocho papadi yodzipatulira.
M'malo mwake, imagwiritsa ntchito malo opangira ma elekitirodi pamakoma a chipindacho kuti ipange mphamvu ya maginito yomwe zida zimatha kulowamo zikafuna mphamvu.
Zipangizo zimagwiritsa ntchito maginito kudzera m'makoyilo, omwe amatha kuphatikizidwa ndi zida zamagetsi monga mafoni am'manja.
Ofufuzawo ati dongosololi limatha kusinthidwa mosavuta kuzinthu zazikulu, monga mafakitale kapena malo osungira, ndikumakumanabe ndi malangizo otetezedwa ndi ma elekitirodi otetezedwa ndi US Federal Communications Commission (FCC).
"Chinachake chonga ichi ndi chosavuta kugwiritsa ntchito m'nyumba zatsopano, koma ndikuganiza kuti kubwezeretsanso n'kotheka," adatero Takuya Sasatani, wofufuza pa yunivesite ya Tokyo komanso wolemba kafukufukuyu.
"Mwachitsanzo, nyumba zina zamalonda zili kale ndi ndodo zothandizira zitsulo ndipo ziyenera kuthetsedwa kupopera makoma pakhoma, zomwe zingakhale zofanana ndi momwe denga limapangidwira."
Olemba kafukufukuyo akufotokoza kuti dongosololi limatha kupereka mphamvu mpaka 50 Watts popanda kupitilira malangizo a FCC kuti anthu awonetsere maginito.

Mphamvu ya maginito imalongosola momwe mphamvu ya maginito imagawira m'dera lozungulira chinthu cha maginito.
Zimaphatikizapo zotsatira za magnetism pa mafoni a m'manja, mafunde ndi maginito.
Dziko lapansi limapanga mphamvu yakeyake ya maginito, yomwe imathandiza kuteteza pamwamba pa cheza choopsa cha dzuwa.
Chinsinsi chothandizira kuti dongosololi ligwire ntchito, Sample akuti, ndikupanga mawonekedwe owoneka bwino omwe amatha kutulutsa mphamvu yamaginito yachipinda pomwe amatsekereza malo owopsa amagetsi omwe amatha kutentha minofu yachilengedwe.
Yankho la gululi limagwiritsa ntchito chipangizo chotchedwa lumped capacitor, chomwe chimayenderana ndi chitsanzo cha lumped capacitance - kumene matenthedwe amachepetsedwa kukhala zotupa.
Kusiyana kwa kutentha mkati mwa chipika chilichonse n'kopanda phindu ndipo kumagwiritsidwa ntchito kale pomanga machitidwe oyendetsera nyengo.
Ma capacitor omwe amaikidwa m'mipando ya khoma amapanga mphamvu ya maginito yomwe imatuluka m'chipindamo pamene ikugwira magetsi mkati mwa capacitor yokha.
Izi zimagonjetseratu zoletsa zamakina amagetsi am'mbuyomu opanda zingwe, omwe anali ochepa popereka mphamvu zambiri pamtunda waung'ono wa mamilimita ochepa, kapena zochepa kwambiri pamtunda wautali, zomwe zitha kuvulaza anthu.
Gululi liyeneranso kupanga njira yowonetsetsa kuti mphamvu yawo ya maginito ikufika pakona iliyonse ya chipindacho, kuchotsa "malo akufa" omwe sangawononge.
Minda ya maginito imakonda kufalikira mozungulira, kupanga mawanga akufa m'zipinda zazikulu komanso zovuta kugwirizanitsa bwino ndi ma coils mu chipangizocho.
"Kujambula mphamvu mumlengalenga ndi koyilo kuli ngati kugwira agulugufe ndi ukonde," adatero Sample, ndikuwonjezera kuti chinyengo ndi "kutengera agulugufe ochuluka momwe angathere kuti azizungulira m'chipindamo momwe angathere."
Pokhala ndi agulugufe angapo, kapena pamenepa, maginito angapo amalumikizana, mosasamala kanthu za komwe ukonde uli, kapena momwe akulozera - mudzagunda chandamale.
Wina amazungulira mzati wapakati wa chipindacho, pamene wina amazungulira m’makona, kuluka pakati pa makoma oyandikana nawo.
Itha kugwiritsidwa ntchito kulipiritsa chipangizo chilichonse chokhala ndi koyilo mkati, chofanana ndi kachitidwe kamene kamagwiritsidwa ntchito ndi mapadi othamangitsira opanda zingwe - koma opanda pad.
Ofufuzawo sananene kuti teknolojiyi ingawononge ndalama zingati, chifukwa ikadali kumayambiriro kwa chitukuko, koma "zidzatenga zaka" ndipo zikhoza kubwezeretsedwanso ku nyumba zomwe zilipo kale kapena kuphatikizidwa m'nyumba zatsopano zikapezeka pakati.
Malinga ndi Zitsanzo, njira iyi imachotsa malo akufa, kulola zida kukoka mphamvu kuchokera kulikonse mumlengalenga.
