Likristale tsa quartz, ka lebaka la phello ea tsona e ikhethang ea piezoelectric, li bapala karolo ea bohlokoa masimong a mangata. Litšebeliso tsa bona li na le likarolo tse ngata tse fapaneng- tsa theknoloji e phahameng, ho kenyeletsoa le tsa elektroniki, likhokahano, le sebaka sa sefofane.
1.Quartz Crystal Oscillators
quartz crystal oscillator e sebelisa kristale ea quartz joalo ka motheo oa maqhubu a resonant-a khethiloeng. Oscillator ena e hahiloe ka ho seha kristale ea quartz hantle hore e be lilae tse tšesaane le ho hokela lipoleiti tsa tšepe holim'a tsona. Molao-motheo oa eona oa ts'ebetso o ipapisitse le phello e fapaneng ea piezoelectric: likristale tsa quartz li sisinyeha ka mokhoa o ts'oanelang tlas'a tšusumetso ea sebaka se seng sa motlakase. Hobane kristale e 'ngoe le e' ngoe ea quartz e na le maqhubu a itseng a tlhaho a ho sisinyeha, resonance e etsahala ha sebaka sa motlakase se sebelisitsoeng se lumellana le maqhubu ana. Tšobotsi ena e etsa hore likristale tsa quartz e be khetho e nepahetseng bakeng sa li-circuits tse ikhethileng- tse phahameng tse resonant{6}. Li-oscillator tsa quartz crystal oscillator, ka lebaka la botsitso ba tsona ba khafetsa, li bapala karolo ea bohlokoa lisebelisoa tse ngata, ho kenyeletsoa lijenereithara tse tloaelehileng tsa maqhubu, li-pulse counters le lioache tsa quartz.
2. Quartz Crystal Microbalance
Quartz Crystal Microbalance (QCM) ke sesebelisoa se sebelisang phello ea piezoelectric ea kristale ea quartz ho lekanya liphetoho ho boima ba holim'a electrode. Ho tloha ha e qala ka bo-1960, e fetohile sesebelisoa se matla sa ho lemoha boima ba nanogram{2}ka lebaka la kutlo ea eona e phahameng haholo. Molao-motheo oa eona oa ho sebetsa ke hore phetoho ea boima bo holim'a metsi a quartz crystal electrode e tla fetoloa ho fetoha ha maqhubu a pontšo ea motlakase oa potoloho ea oscillation. Ts'ebetso ena e hlahlobjoa ke lisebelisoa tse ling tse joalo ka likhomphutha ho fumana liphetho tse phahameng- tsa tekanyo e nepahetseng. Ka hona, quartz crystal microbalance e phetha karolo ea bohlokoa likarolong tse ngata tse kang meriana, indasteri ea lik'hemik'hale, lijo, biomedicine, tlhokomelo ea tikoloho, indasteri le sesole.
3. Piezoelectric biosensor
(1) Piezoelectric immunosensor
Molao-motheo oa ts'ebetso oa piezoelectric immunosensor ke ho lokisa li-antibodies kapa li-antigen holim'a kristale ea quartz le ho sebelisa karabelo e khethehileng ea kamano pakeng tsa antigen le antibody. Ha antigen kapa antibody e lokelang ho lekanyetsoa e sebelisana le ntho e tsitsitseng ea ho lemoha 'me e hlahisa papatso e khethehileng, boima ba bokaholimo ba kristale bo tla eketseha ho latela. Phetoho ena e ka shejoa ka phetoho ea khafetsa ea kutlo, ka hona ho lekanya palo ea li-anti-anti-adsorbed kapa antigen.
(2) Piezoelectric gene sensor
Molawana wa motheo wa sensara ya gene ya piezoelectric bakeng sa ho lemoha DNA ke ho lokisa-motho o le mong wa DNA probe sebakeng sa kristale. Ha tlhahlamano ea DNA e tla lemohuoa e tsamaisana le eona, hybridization reaction e etsahala ho chip ho theha DNA e habeli-ea likhoele. Ts'ebetso ena e tla lebisa ho eketseha ha boima ba kristale le liphetoho ho viscoelasticity ea holim'a metsi. Liphetoho tsena li ka lekanyetsoa ka phetoho ea khafetsa ea sensor le tlhahlobo ea marang-rang.
