Teeb meem kev mloog?Muab koj lub tsho rau.Ib tsab ntawv tshawb fawb luam tawm los ntawm British phau ntawv journal Nature ntawm 16th tau tshaj tawm tias cov ntaub uas muaj cov fibers tshwj xeeb tuaj yeem kuaj pom lub suab zoo.Kev tshoov siab los ntawm lub ntsej muag zoo nkauj ntawm peb lub pob ntseg, cov ntaub no tuaj yeem siv los ua ob txoj kev sib txuas lus, pab kev mloog lus, lossis saib xyuas kev ua haujlwm ntawm lub plawv.
Raws li txoj cai, tag nrho cov ntaub yuav co teb rau cov suab nrov, tab sis cov kev vibrations no yog nano scale, vim hais tias lawv yog me me heev yuav tsum tau perceived.Yog tias peb tsim cov ntaub uas tuaj yeem ntes thiab ua cov suab nrov, nws yuav tsum tau qhib ntau cov ntaub ntawv siv tau los ntawm kev suav cov ntaub rau kev ruaj ntseg thiab tom qab ntawd mus rau biomedicine.
Pab pawg tshawb fawb MIT tau piav qhia txog kev tsim ntaub tshiab lub sijhawm no.Kev tshoov siab los ntawm cov qauv ntawm pob ntseg, cov ntaub no tuaj yeem ua haujlwm raws li lub microphone rhiab heev.Tib neeg pob ntseg tso cai rau kev co tsim los ntawm lub suab kom hloov mus rau hauv hluav taws xob teeb liab los ntawm cochlea.Cov qauv tsim no yuav tsum tau xaws cov ntaub tshwj xeeb hluav taws xob - piezoelectric fiber ntau rau hauv cov xov paj ntaub, uas tuaj yeem hloov lub siab nthwv dej ntawm lub suab nrov mus rau hauv kev vibration.Cov fiber ntau no tuaj yeem hloov cov kev vibrations rau hauv hluav taws xob, zoo ib yam li kev ua haujlwm ntawm cochlea.Tsuas yog ib qho me me ntawm qhov tshwj xeeb piezoelectric fiber ntau tuaj yeem ua rau cov ntaub ntawv suab rhiab heev: fiber ntau tuaj yeem ua rau fiber ntau microphone ntawm kaum ob square meters.
Lub microphone fiber ntau tuaj yeem ntes cov suab paj nruag tsis muaj zog li tib neeg hais lus;Thaum woven rau hauv ob sab phlu ntawm lub tsho, cov ntaub tuaj yeem pom cov yam ntxwv ntawm lub plawv dhia ceev ntawm tus neeg hnav;Ntau qhov nthuav, cov fiber ntau no tuaj yeem ua lub tshuab ntxhua khaub ncaws thiab muaj drapability, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv hnav.
Pab neeg tshawb fawb tau pom peb qhov tseem ceeb ntawm cov ntaub ntawv no thaum woven rau hauv lub tsho.Cov khaub ncaws tuaj yeem ntes cov kev taw qhia ntawm lub suab nrov;Nws tuaj yeem txhawb ob txoj kev sib txuas lus ntawm ob tus neeg - ob leeg hnav cov ntaub no uas tuaj yeem ntes suab;Thaum cov ntaub kov ntawm daim tawv nqaij, nws tuaj yeem saib xyuas lub plawv.Lawv ntseeg tias qhov kev tsim qauv tshiab no tuaj yeem siv rau ntau yam xwm txheej, suav nrog kev ruaj ntseg (xws li kev tshawb nrhiav qhov chaw ntawm rab phom), kev mloog lus rau cov neeg siv lub mloog pob ntseg, lossis kev saib xyuas lub sijhawm ntev ntawm cov neeg mob plawv thiab ua pa.
