Cov neeg yos hav zoov tsis hnav khaub ncaws camouflage kom sib xyaw nrog lawv ib puag ncig. Tab sis thermal camouflage - los yog qhov tsos ntawm qhov kub thiab txias ib puag ncig - yog qhov nyuaj dua. Tam sim no cov kws tshawb fawb, tshaj tawm hauv ACS cov ntawv xov xwmNano Cov Ntawv, tau tsim ib qho system uas tuaj yeem kho nws cov thermal tsos kom sib xyaw nrog qhov sib txawv ntawm qhov kub thiab txias hauv ib lub vib nas this.

Feem ntau lub xeev-ntawm-lub-kos duab hmo ntuj pom kev yog raws li thermal imaging. Thermal koob yees duab ntes infrared hluav taws xob tawm los ntawm ib yam khoom, uas nce nrog cov khoom kub. Thaum pom los ntawm cov cuab yeej pom kev hmo ntuj, tib neeg thiab lwm yam tsiaj uas muaj ntshav sov sawv tawm tsam qhov chaw txias dua. Yav dhau los, cov kws tshawb fawb tau sim tsim cov thermal camouflage rau ntau yam kev siv, tab sis lawv tau ntsib teeb meem xws li cov lus teb qeeb qeeb, tsis muaj kev hloov pauv mus rau qhov sib txawv ntawm qhov kub thiab qhov yuav tsum tau muaj cov ntaub ntawv nruj. Coskun Kocabas thiab cov neeg ua haujlwm ua haujlwm xav tsim cov khoom siv ceev ceev, yoog raws thiab hloov tau yooj yim.

Cov kws tshawb fawb cov txheej txheem camouflage tshiab muaj cov khoom siv hluav taws xob sab saum toj nrog cov txheej ntawm graphene thiab hauv qab electrode ua los ntawm cov txheej kub kub ntawm cov nylon kub-resistant. Sandwiched nruab nrab ntawm cov electrodes yog ib daim nyias nyias uas ntub nrog cov kua ionic, uas muaj cov ions zoo thiab tsis zoo. Thaum siv hluav taws xob me me, cov ions nkag mus rau hauv graphene, txo cov emission ntawm infrared hluav taws xob los ntawm lub camo nto. Lub kaw lus yog nyias, lub teeb thiab yooj yim rau khoov ib ncig ntawm cov khoom. Pab neeg no tau qhia tias lawv tuaj yeem ua kom sov lub ntsej muag ntawm tus neeg txhais tes. Lawv kuj tuaj yeem ua rau cov cuab yeej thermally indistinguishable los ntawm nws ib puag ncig, nyob rau hauv ob qho tib si warmer thiab txias ib puag ncig. Cov txheej txheem tuaj yeem ua rau cov thev naus laus zis tshiab rau thermal camouflage thiab yoog raws cov cua sov tiv thaiv rau satellites, cov kws tshawb fawb tau hais.
