Kiristaalo Quartz, sababtoo ah saameyntooda piezoelectric ee gaarka ah, waxay door muhiim ah ka ciyaaraan meelo badan. Barnaamijyadoodu waxa ay gaadhaan tiro balaadhan oo ah qaybaha teknoolajiyada sare{1}, oo ay ku jiraan elegtarooniga, isgaarsiinta, iyo hawada sare.
1. Quartz Crystal Oscillators
Oscillator-ka quartz crystal oscillator waxa uu isticmaalaa kiristaalo quartz ah sida xudunta soo noqnoqda resonant - wareegyada xulashada. Oscillator-kan waxa loo dhisay isagoo si sax ah u jarjaraya crystal quartz qaybo khafiif ah oo ku dhejinaya taarikada biraha dusha sare. Mabda'a hawleedkeedu wuxuu ku salaysan yahay saamaynta piezoelectric ee rogaal celiska ah: kiristaalo quartz waxay u gariiraan si farsamaysan iyadoo ay saamayn ku leedahay beer koronto oo kale. Sababtoo ah kareemka quartz kastaa wuxuu leeyahay soo noqnoqoshada gariir dabiici ah oo gaar ah, resonance waxay dhacdaa marka goobta korantada ee la dabaqay ay la mid tahay inta jeer een. Dabeecaddani waxay ka dhigaysa kiristaalo quartz doorasho ku habboon-soo noqnoqoshada saxda ah{6}} wareegyada xulashada. Quartz crystal oscillators, iyadoo ay ugu wacan tahay xasilloonida soo noqnoqda ee aadka u wanaagsan, waxay door muhiim ah ka ciyaaraan aalado badan, oo ay ku jiraan soosaarayaasha soo noqnoqda caadiga ah, xisaabiyeyaasha garaaca wadnaha, iyo saacadaha quartz.
2. Quartz Crystal Microbalance
Quartz Crystal Microbalance (QCM) waa qalab isticmaala saamaynta piezoelectric ee quartz crystal si loo cabbiro isbeddelada cufka dusha sare ee korantada. Tan iyo markii la hirgaliyay horraantii 1960-meeyadii, waxa ay noqotay qalab awood badan oo loogu talagalay nanogram{2}} ogaanshaha heerka tirada badan sababtoo ah dareenkiisa aadka u sarreeya. Mabda'a shaqadeeda ayaa ah in isbeddelka xajmiga dusha sare ee quartz crystal electrode loo rogi doono isbeddelka soo noqnoqda ee calaamadda korantada ee wareegga oscillation. Nidaamkan ayaa markaa lagu falanqeeyaa qalab caawiya sida kombiyuutarada si loo helo natiijooyinka cabbirka saxda ah ee sare-. Sidaa darteed, mikrobalance-ka quartz crystal wuxuu door muhiim ah ka ciyaaraa dhinacyo badan sida daawada, warshadaha kiimikada, cuntada, biomedicine, la socodka deegaanka, warshadaha iyo militariga.
3. Biosensor Piezoelectric
(1) difaaca jirka ee Piezoelectric
Mabda'a shaqada ee piezoelectric immunosensor waa in la hagaajiyo unugyada difaaca jirka ama antigens ee dusha sare ee crystal quartz oo la isticmaalo falcelinta xiriirka gaarka ah ee u dhexeeya antigen iyo antibody. Marka antigen-ka ama antibody-ka la cabbiro ay la falgalaan walaxda aqoonsiga go'an oo ay soo saaraan xayeysiis gaar ah, culeyska dusha sare ee crystals ayaa u kordhin doona si waafaqsan. Isbeddelkan waxaa lagula socon karaa isbeddelka soo noqnoqda ee dareemayaasha, si loo go'aamiyo qadarka antibody-ga la adsorbed ama antigen.
(2) Dareemaha hidda-wadaha Piezoelectric
Mabda'a aasaasiga ah ee dareemayaasha hidda-wadaha piezoelectric ee ogaanshaha DNA waa in la hagaajiyo baaritaanka DNA ee kelida ah- ee dusha sare ee crystal. Marka isku xigxiga DNA-da ee la ogaanayo uu la mid yahay, falcelinta isku-dhafan waxay ku dhacdaa chip-ka si ay u sameeyaan labanlaaban-DNA. Habkani wuxuu u horseedi doonaa kororka cufnaanta crystal iyo isbeddelka viscoelasticity dusha sare. Isbeddelladan waxaa lagu qiyaasi karaa isbeddelka soo noqnoqda ee dareemayaasha iyo falanqaynta shabakadda.
