Cov kws tshawb nrhiav tau ua tiav ib qho kev tsim khoom tseem ceeb nrog cov ntawv cim RFID luam tawm uas raug nqi qis dua $ 0.002 ib chav - txo 90% ntawm cov ntawv cim ib txwm muaj. Kev tsim kho tshiab no tsom mus rau cov kav hlau txais xov graphene uas ua tiav 8 dBi nce txawm tias nws tuab 0.08 hli, sib xws nrog cov kwj deg rov ua dua tshiab.

Qhov kev tshawb pom tshiab no ua rau muaj kev cim npe ntau ntawm cov khoom siv pheej yig uas yav dhau los suav tias tsis yooj yim ua tau. Kev sim tshuaj qhia tau tias muaj kev cia siab: Kev sib xyaw ua ke ntawm cov pob blister tso cai rau cov neeg mob kom paub tseeb tias cov tshuaj yog qhov tseeb thaum taug qab kev ua raws li cov tshuaj noj los ntawm cov khoom siv NFC.

Ib pab pawg neeg tshawb fawb txog cov khoom siv ntawm ib lub tsev kawm ntawv tshawb fawb hauv Tebchaws Meskas tau tsim cov txheej txheem plasma-enhanced chemical vapor deposition (PECVD) los txuas cov khaubncaws sab nraud povtseg graphene ncaj qha rau ntawm cov khoom siv biodegradable. "Peb cov txheej txheem ua tiav 98% kev siv cov khoom siv piv rau 60% hauv cov txheej txheem etching ib txwm muaj," tus thawj coj ntawm qhov project tau hais, uas nws pab neeg nyuam qhuav tau txais $ 15 lab nyiaj los ntawm tsoomfwv rau cov chaw tsim khoom sim.

Cov txiaj ntsig ntawm thev naus laus zis txuas ntxiv mus rau qhov kev xa khoom: Cov pab pawg ib puag ncig qhia txog lub peev xwm los txo cov khib nyiab hluav taws xob los ntawm 220,000 tons txhua xyoo los ntawm cov cim eco-tags pov tseg uas lwj hauv 90 hnub.
