ceramics Piezoelectric waa nooc ka mid ah walxaha dhoobada shaqeynaya oo u beddeli kara tamarta farsamada iyo tamarta korantada midba midka kale. Waa saamayn piezoelectric ah. Marka laga soo tago piezoelectricity, ceramics piezoelectric waxay sidoo kale leeyihiin dielectricity, elasticity, iwm, kuwaas oo si weyn loogu isticmaalay sawirada caafimaadka, dareemayaasha Acoustic, transducers acoustic, matoorrada ultrasonic, iwm.
dhoobada Piezoelectric waxaa inta badan loo isticmaalaa soo saarida transducers ultrasonic, transducers acoustic biyaha hoostooda, transducers electroacoustic, filtarrada dhoobada, transformers dhoobada, takoori dhoobada, koronto sare ee koronto, qalabka infrared, qalabka korka acoustic acoustic qalabka, electro-optic Aaladaha, shido iyo qarxinta, piezoelectric gyros, iwm, looma isticmaalo oo keliya tignoolajiyada sare beeraha, laakiin sidoo kale nolol maalmeedka si loogu adeego dadka iyo in loo abuuro nolol wanaagsan dadka.
Dagaalkii IIaad ee Adduunka, BaTiO3 ceramics ayaa la helay, iyo agabka piezoelectric iyo codsiyadoodu waxay sameeyeen horumar xilli-gaar ah. Iyonano BaTiO3 budadasuurtogal ka dhig in la soo saaro BaTiO3 Ceramic oo leh sifooyin horumarsan.
Dhammaadkii qarnigii 20-aad, saynisyahano maaddo ah oo ka kala yimid adduunka oo dhan ayaa bilaabay inay sahamiyaan walxo cusub oo ferroelectric ah. Markii ugu horeysay, fikradda qalabka nano ayaa lagu soo bandhigay daraasadda qalabka piezoelectric, taas oo ka dhigtay cilmi-baarista iyo horumarinta qalabka piezoelectric, qalab shaqeynaya, oo wajahaya horumar weyn, oo muujinaya alaabta. Isbeddelka wax qabadku waa in qalabka farsamada, sifooyinka piezoelectric, iyo sifooyinka dielectric si weyn loo hagaajiyay. Tani waxay shaki la'aan saameyn togan ku yeelan doontaa waxqabadka transducer.
Waqtigan xaadirka ah, habka ugu muhiimsan ee qaadashada fikradda mitirka nano ee qalabka piezoelectric functional waa in la wanaajiyo sifooyinka qaarkood ee alaabta piezoelectric (ku dar nanoparticles kala duwan si ay u sameeyaan nano dhismooyinka qalabka piezoelectric) iyo (isticmaalka piezoelectric nanopowders ama Nanocrystals iyo polymers waxaa lagu sameeyaa qalab isku dhafan hab gaar ah) 2 hab. Tusaale ahaan, qaybta alaabta ee Jaamacadda Thanh Ho, si loo hagaajiyo polarization saturation iyo polarization hadhaaga ah ee alaabta dhoobada ferroelectric, Ag nanoparticles ayaa lagu daray si loo diyaariyo "nano-multiphase ceramics ferroelectric ceramics oo ku salaysan nanoparticles biraha / dhoobada ferroelectric"; Sida nano alumina (AL2O3) / PZT,nano zirconium dioxide (ZrO2)/ PZT iyo nano kale oo isku dhafan dhoobada ferroelectric si loo yareeyo walxaha ferroelectric asalka ah ee k31 iyo kordhinta adkaanta jabka; Qalabka nano piezoelectric iyo polymers si wadajir ah loo helo nano piezoelectric walxo isku dhafan. Waqtigaan waxaan dooneynaa inaan barano diyaarinta ceramics piezoelectric anagoo isku dhafan nano piezoelectric budada leh nano organic additives, ka dibna baranaya isbeddelada guryaha piezoelectric iyo sifooyinka dielectric.
Waxaan rajeyneynaa codsiyo badan oo nanoparticles ah oo ku jira ceramics piezoelectric!
