Abantu baseMelika bahlongoze ukuqoqa amandla e-inthanethi Yezinto kusukela kukazibuthe yezintambo zikagesi eziseduze

Isihloko sokukhipha ugesi “emoyeni” - emsindweni we-electromagnetic, ukudlidliza, ukukhanya, umswakama nokunye okuningi - sikhathaza abacwaningi abangamasosha kanye nozakwabo abagqoke umfaniswano. Igalelo lakho kulesi sihloko inikezwe ososayensi kusuka ePennsylvania State University. Kusuka kumagnetic wezintambo zikagesi eziseduze, bakwazi ukukhipha ugesi ngamandla ama-milliwatts amaningana, okwanele, isibonelo, ukunika amandla ngokuqondile iwashi le-alamu yedijithali.

Ishicilelwe kumagazini Amandla Nesayensi Yezemvelo Kulesi sihloko, ososayensi bakhulume ngezibalo kanye nokukhiqizwa kweziguquli ezikhethekile zamasimu kagesi zibe wamanje kagesi. Isici sezimayini senziwe ngendlela yepuleti elincane le-multilayer elinozibuthe unomphela ekugcineni kwamahhala (omunye umkhawulo wepuleti ulungiswe ngokuphephile). Ipuleti ngokwalo liqukethe ungqimba lwe-piezoelectric kanye nongqimba lwe i-magnetostrictive impahla (Fe85B5Si10 Metglas).

Izinto ezithinta uzibuthe ziyathakazelisa ngoba lapho isimo sikazibuthe sishintsha, ivolumu yayo kanye nobukhulu bomugqa kuyashintsha. I-hum ecasulayo yamakhoyili kumakhadi wevidiyo, njengomthetho, izinguquko ze-magnetostrictive kuma-cores. Endaweni eshintshanayo kazibuthe yezintambo zikagesi ezivamile ezinemvamisa engu-50 noma engu-60 Hz, ipuleti le-Metglas liqala ukudlidliza futhi lishintshe ipuleti le-piezoelectric elinamathiselwe kulo. I-current iqala ukugeleza kunethiwekhi exhunywe kumapuleti.

Kodwa-ke, i-magnetostrictive material ehlanganiswe ne-piezoelectric ikhiqiza kuphela u-16% kagesi okhiqizwa yisici. Okukhiphayo okuyinhloko kuvela ekuzulisekeni kukazibuthe unomphela endaweni ye-electromagnetic. Kuthiwa i-voltage ephezulu kuyo yonke into ifinyelela ku-80 V endaweni engama-300 μT. Kodwa into ebaluleke kakhulu ukuthi into ethuthukisiwe ingakhiqiza amandla anele ukuze inikeze amandla ngokuqondile iwashi ledijithali emkhakheni ongaphansi kuka-50 μT ebangeni elingama-20 cm ukusuka ku-wiring kagesi.

Ososayensi basePennsylvania State University benze ucwaningo lwabo kanye nabacwaningi abavela eVirginia Tech kanye neqembu elivela ku-US Army Combat Capabilities Development Command.
