Intraoral koob yees duab tshwm sim los ntawm kab qhov muag

Kaus lim qab teb: Pab neeg tshawb fawb los ntawm Kauslim Kauslim Lub Tsev Kawm Txuj Ci Hauv Kev Tshawb Fawb thiab thev naus laus zis (KAIST) thiab Kauslim lub koom haum ntawm Optical Technology (KOPTI) tau tsim ib lub koob yees duab intraoral uas tuaj yeem ua raws li qhov muag ntawm kab.

Coj los ntawm KAIST Prof Ki-Hun Jeong, pab pawg tsim cov biologically tshwm sim intraoral koob yees duab (BIOC) nrog lub kaum sab xis ntawm kev pom dav thiab qhov tob tob ntawm thaj teb.

A tshawb fawb daim ntawv ntawm kab-inspired koob yees duab technology tsis ntev los no tau luam tawm nyob rau hauv Phau ntawv Journal of Optical Microsystems, ib phau ntawv xov xwm ntawm International Society of Optical Engineers.

Mimicking kab qhov muag tus yam ntxwv zoo heev

Raws li pab pawg, tus kab lub qhov muag yog qhov pom tsis meej ntawm cov lo ntsiab muag me me thiab muaj qhov pom tseeb pom tseeb xws li qhov tob ntawm kev saib thiab qhov tob ntawm daim teb.

Cov cuab yeej siv kho hniav zoo nkauj feem ntau txwv los ntawm kev siv cov cuab yeej tsis yooj yim xws li tsom iav thiab sab plhu retractors, lawv piav qhia.

Txhawm rau kom tau txais cov duab ntawm cov hniav ntawm ntau lub kaum sab xis rau kev tshuaj xyuas niaj hnub - suav nrog txoj cai / sab laug buccal thiab maxillary / mandibular occlusal - cov koob yees duab hauv lub cev yuav ua rau tsis xis nyob rau tus neeg mob, vim tus kws kho hniav yuav tsum tau muab daim iav rau hauv lub qhov ncauj kom ntes tau qhov cuam tshuam. hniav duab los ntawm lub koob yees duab tuav.

Technology imitating biology

Pab neeg tshawb fawb tau tsim lub koob yees duab lub qhov ncauj ultra-thin siv lub lens convex, concave lens, inverted micro lens array (iMLA), thiab CMOS duab sensor.

Lub convex thiab concave lo ntsiab muag tau nce lub kaum sab xis ntawm qhov pom mus rau 143 degrees, thiab iMLA tau ua lub luag haujlwm hauv kev txo qis qhov muag pom. Nws muaj peev xwm kom tau txais cov duab meej yam tsis muaj duab plooj txawm tias nyob ze, ua raws li qhov pom kev ua haujlwm ntawm kab nrog qhov tob tsis kawg ntawm thaj teb.

Vim lub koob yees duab me me thiab nyias nyias, nws tuaj yeem soj ntsuam cov hniav txawm tias nyob hauv thaj chaw anatomically nqaim.

"Lub koob yees duab tsim lub sijhawm no yuav tsis tsuas yog pab txhawb rau kev txhim kho biomedical engineering technology, tab sis kuj tseem yuav nthuav dav nws daim ntawv thov rau ntau yam xws li kev soj ntsuam, smartphones, thiab drones," hais tias cov kws tshawb fawb.

Kev txhim kho ntawm cov koob yees duab kab-inspired yav dhau los

Ntau hom kab kab ob lub qhov muag muaj qhov pom kev zoo tshaj plaws, xws li lub ntsej muag dav dav thiab qhov tob ntawm qhov loj nrog cov khoom siv hauv nruab nrog cev ua los ntawm cov lo ntsiab muag me me.

Yog li ntawd, cov koob yees duab me me uas tau tshoov siab los ntawm kab tuaj yeem daws cov teeb meem ntawm cov koob yees duab compact. Txawm li cas los xij, yav dhau los tsim cov koob yees duab kab-tso rau hauv kev txom nyem tsis zoo nrog rau kev daws teeb meem qis lossis kev ua haujlwm tsawg.

Lub BIOC suav nrog kev teeb tsa tshiab ntawm convex-concave lens thiab inverted microlens arrays (iMLA) thiab ib qho CMOS duab sensor ntawm lub rooj tsav xwm hloov pauv hloov pauv hauv ib lub hnab tes.

Dhau li ntawm kev ua kom pom kev pom thiab txo qhov pom qhov tsis zoo los ntawm txoj cai scaling, lub koob yees duab tshiab kov yeej ntau yam teeb meem ntev ntawm cov koob yees duab hauv lub cev, xws li txwv qhov tob-ntawm- teb, tuab tag nrho-ntev-ntev, thiab txwv kev ua haujlwm imaging.

Los ntawm cov kab ke pom kev sib txawv, BIOC muaj ntau yam kev kho hniav imaging, xws li siab dynamic ntau, 3D qhov tob, thiab autofluorescence imaging.
