Niaj hnub no, kev tswj hwm tus kheej thiab tus kheej - lub zog ntsuas hluav taws xob tau siv thoob plaws ntau thaj chaw xws li Is Taws Nem ntawm Yam (IoT), kev lag luam automation, lub nroog ntse, thiab kev saib xyuas kev noj qab haus huv (SHM). Nyob rau hauv lub moj khaum no, kev tshawb fawb kev kawm tau pioneered kev ruaj ntseg thiab ncig kev daws teeb meem kom tau raws li lub zog xav tau ntawm cov khoom siv hluav taws xob me me.
Raws li MEMS Consulting, cov kws tshawb fawb ntawm University of Perugia, Ltalis, tsis ntev los no tau npaj ib txoj hauv kev tshiab rau kev ntsuas qhov kub thiab txias ntawm cov hlwb thiab lawv ib puag ncig. Txoj hauv kev no siv hluav taws xob hluav taws xob los ntawm ib leeg flounder nqaij fiber ntau. Qhov zoo tshaj plaws RLC Circuit Court yog embedded nyob rau hauv lub cell, qhov twg lub capacitor ua hauj lwm raws li ob qho tib si lub zog cia chav tsev thiab ib tug kub sensor, leveraging nws inherent thermal rhiab heev. Cov ntaub ntawv tshawb fawb tau lees paub tias cov txheej txheem tsim tau wirelessly xa mus rau qhov kub thiab txias uas siv lub zog sau los ntawm cov cell membrane thiab ua haujlwm nyob rau hauv cov kab mob lom (30℃txog 50 degree). Qhov no tus kheej -lub zog ntsuas qhov ntsuas kub muaj peev xwm los txhim kho biomedical sensing thiab tsis yog -invasive tej thaj chaw deb ntsuas kub. Cov kev tshawb fawb tshawb fawb tau luam tawm nyob rau hauv phau ntawv journal Nano Energy nyob rau hauv lub npe "Tus kheej-Powered Temperature Sensors Harnessing Membrane Potential of Living Cells."
Hauv kev ua haujlwm no, cov kws tshawb fawb tau txiav txim siab tias cov nqaij fibers tuaj yeem ua kom muaj qhov sib txawv ntawm daim nyias nyias, vim tias lawv lub peev xwm so tuaj yeem ncav cuag -90 mV. Lawv tau tshawb nrhiav kev siv lub peev xwm ntawm daim nyias nyias ntawm cov leeg nqaij ib leeg los ntsuas qhov ua tau ntawm kev siv tus kheej -powered biosensor technology. LTspice simulations ua ntej tau ua hauj lwm los tsim ib lub wireless kev sib txuas lus uas muaj peev xwm ntsuas cov kab mob lom neeg ntawm kev txaus siab-kub. Txog rau qhov kawg no, cov kws tshawb fawb tau ua qauv thiab ua kom zoo dua RLC Circuit Court uas nws oscillation zaus nws txawv nrog cellular kub. Qhov no tau ua rau kev tsim khoom thiab kev sim ntsuas qhov ntsuas kub ncaj qha los ntawm cov leeg nqaij fibers nyob rau hauv ntau yam kev sim, tso cai rau kev ntsuam xyuas ntawm lawv qhov kev ua tau zoo thiab kev ntseeg tau.
Bioelectric Generator thiab Energy Harvesting Circuit
Los ntawm cov kws tshawb fawb qhov kev sim teeb tsa, kev hloov pauv hauv capacitor C1 tuaj yeem siv tau los siv cov zaus oscillation zaus ntawm qhov kub sib txawv. Txij li thaum cov leeg nqaij pob txha muaj nyob thoob plaws hauv lub cev tsiaj txhu, cov kws tshawb fawb txoj kev ua rau nws tus kheej -lub zog ntsuas qhov ntsuas kub kom cog rau qhov twg hauv tib neeg lub cev. Qhov no ua kom yooj yim saib xyuas thiab nkag siab txog qhov hloov pauv ntawm qhov kub ntawm lub cev, uas tuaj yeem cuam tshuam qhov cuam tshuam rau ntau yam txheej txheem lom neeg -xws li kev loj hlob ntawm cov qog nqaij hlav hauv lub mis- lossis rau kev sib xyaw bio- cov neeg hlau rau kev xa tshuaj.
Kev sim teeb tsa
Cov kws tshawb fawb kuj tau ua qhov kev sim sim ntawm lub zog tsim los ntawm cov hlwb lom. Lawv cais cov nqaij ntshiv ntawm cov nas thiab ntxig ib qho intracellular electrode rau hauv ib qho fiber ntau, ua kom pom qhov ua tau ncaj qha los ntawm cov hluav taws xob hluav taws xob los ntawm cov cell membrane. Thaum kuaj, lawv tau sau ib qhov hluav taws xob ntawm -60 mV thiab 2 µJ ntawm lub zog hluav taws xob, uas tau muab cia rau hauv 1 mF capacitor thiab thaum kawg siv los siv lub zog rau lub ntsuas hluav taws xob. Cov kws tshawb fawb tau pom tias cov leeg pob txha ua tau zoo dua li cov oocytes siv hauv kev tshawb fawb yav dhau los.
Them lub capacitor ntawm flounder nqaij fibers
Cov kws tshawb fawb tau piv cov txiaj ntsig kev sim nrog RLC qauv Circuit Court, qhia pom kev pom zoo ntawm cov ntaub ntawv ntsuas thiab kev kwv yees theoretical. Txawm li cas los xij, qhov tsis tshua muaj hluav taws xob tau txais los ntawm cov fibers tuaj yeem tsim teeb meem rau kev siv qis - fais fab hluav taws xob cuam tshuam rau kev sib txuas lus wireless. Txawm li cas los xij, lub tshuab hluav taws xob tsis siv neeg ntsuas kub uas tau npaj tseg hauv txoj kev tshawb fawb no siv cov khoom tshwj xeeb uas tau xaiv cia capacitor txuas nrog bio- lub tshuab hluav taws xob thiab tuaj yeem sib txuas lus nrog tus txais sab nraud ntawm qhov ze (10 hli).
Qhov ntsuas kub no, ib zaug ntsuas, xa cov ntaub ntawv kub ntawm 160 Hz bandwidth thoob plaws thaj tsam ntawm chav tsev kub mus rau qhov kub thiab txias (30℃txog 50 degree). Yav tom ntej miniaturization tuaj yeem ua rau siab dua - qhov ntsuas qhov kub thiab txias, tab sis qhov no yuav tsum ua tib zoo tsim cov hluav taws xob hluav taws xob hluav taws xob kom txo tau cov kab mob parasitic thiab txo lub zog ntxiv.
Kub Sensor yam ntxwv
Hauv cov ntsiab lus, cov kws tshawb fawb tau hais txog qhov muaj peev xwm ntawm cov hlwb lom neeg ua lub zog rau cov ntawv me me - nplai bio- embedded applications. Los ntawm kev siv cov kev ua haujlwm ntawm cov hlwb muaj sia-tshwj xeeb yog cov tsiaj cell (cov leeg nqaij fibers)-tshuaj lub zog tuaj yeem hloov mus rau hauv hluav taws xob, ua kom muaj kev txhim kho ntawm tus kheej -powered bio-embedded sensors. Piv nrog rau cov roj teeb uas siv tau thiab cov khoom siv hluav taws xob kinetic, qhov kev daws teeb meem no muaj qhov zoo sib xws, ua rau txoj hauv kev rau yav tom ntej kev koom ua ke ntawm bio-embedded electronics rau hauv cov kab mob lom. Cov thev naus laus zis no tau cog lus rau kev tsim cov chav kawm ntawm bio{10}} cov khoom siv hluav taws xob uas muaj peev xwm tuaj yeem cuam tshuam ncaj qha nrog cov hlwb hauv cov kab mob uas muaj sia nyob. Kev tshawb fawb ntxiv thiab kev txhim kho hauv daim teb no yuav ua rau muaj kev nce qib hauv cov txuj ci sau hluav taws xob thiab kev hloov pauv ntawm bio-embedded electronics.
