Lub ntsiab lus ntawm kev rho tawm hluav taws xob los ntawm "cua" - los ntawm lub suab nrov electromagnetic, kev vibrations, lub teeb, av noo thiab ntau ntxiv - kev txhawj xeeb rau cov neeg tshawb nrhiav thiab lawv cov npoj yaig hauv cov khaub ncaws. Koj qhov kev pab cuam rau lub ncauj lus no los ntawm Pennsylvania State University. Los ntawm cov chaw sib nqus ntawm cov hluav taws xob nyob ze, lawv muaj peev xwm rho tawm hluav taws xob nrog lub zog ntawm ob peb milliwatts, uas yog txaus, piv txwv li, ncaj qha hluav taws xob lub tswb moos.
Tshaj tawm hauv phau ntawv xov xwm Hauv tsab xov xwm, cov kws tshawb fawb tau tham txog kev suav thiab kev tsim khoom tshwj xeeb ntawm cov khoom siv hluav taws xob electromagnetic rau hauv hluav taws xob tam sim no. Lub ntsiab mining yog tsim nyob rau hauv daim ntawv ntawm ib tug multilayer nyias phaj nrog ib tug ruaj khov hlau nplaum nyob rau hauv lub dawb kawg (qhov kawg ntawm lub phaj yog ruaj ntseg ruaj). Lub phaj nws tus kheej muaj ib txheej piezoelectric thiab ib txheej ntawm Khoom siv (Fe85B5Si10 Metglas).
Cov khoom siv Magnetostrictive yog qhov nthuav vim hais tias thaum lub xeev ntawm magnetization hloov, nws ntim thiab linear qhov ntev hloov. Qhov kev ntxhov siab ntawm coils hauv daim npav video yog, raws li txoj cai, kev hloov pauv magnetostrictive hauv cov cores. Nyob rau hauv alternating magnetic teb ntawm pa hluav taws xob thaiv nrog ib tug zaus ntawm 50 los yog 60 Hz, lub Metglas phaj pib vibrate thiab deform lub piezoelectric phaj glued rau nws. Tam sim no pib ntws hauv lub network txuas nrog cov phiaj.
Txawm li cas los xij, cov khoom siv magnetostrictive ua ke nrog piezoelectric tsuas yog ua rau 16% ntawm cov hluav taws xob tsim los ntawm lub caij. Lub ntsiab tso zis yog los ntawm oscillation ntawm ib tug mus tas li hlau nplaum nyob rau hauv ib tug electromagnetic teb. Nws tau thov tias qhov siab tshaj qhov hluav taws xob thoob plaws lub caij ncav cuag 80 V hauv thaj tsam ntawm 300 ΞΌT. Tab sis qhov tseem ceeb tshaj plaws yog tias cov khoom tsim tau tuaj yeem tsim lub zog txaus los ncaj qha rau lub moos digital hauv thaj tsam tsawg dua 50 ΞΌT ntawm qhov deb ntawm 20 cm los ntawm kev xaim hluav taws xob.
Cov kws tshawb fawb los ntawm Pennsylvania State University tau ua lawv txoj kev tshawb fawb ua ke nrog cov kws tshawb fawb los ntawm Virginia Tech thiab ib pab pawg los ntawm US Army Combat Capabilities Development Command.
