Makristasi eQuartz, nekuda kweakasarudzika piezoelectric maitiro, anoita basa rakakosha muminda yakawanda. Zvishandiso zvavo zvinotambanudzira chikamu chakasiyana-siyana che-chetekinoroji, kusanganisira zvemagetsi, zvekufambiswa kwemashoko, uye zvemuchadenga.
1.Quartz Crystal Oscillators
A quartz crystal oscillator inoshandisa quartz crystal semusimboti we resonant frequency-selective circuit. Iyi oscillator inovakwa nekunyatsocheka kristaro yequartz kuita zvidimbu zvitete uye kuisa marata esimbi kune yavo. Kushanda kwayo musimboti wakavakirwa pane inverse piezoelectric mhedzisiro: makristasi equartz anodedera zvine mutsindo pasi pesimba renzvimbo yemagetsi. Nekuti yega yega quartz kristaro ine chaiyo yakasikwa vibration frequency, resonance inoitika kana yakashandiswa yemagetsi munda inofananidzira iyi frequency. Chimiro ichi chinoita kuti makristasi equartz ave sarudzo yakanaka kune yakakwirira-precision resonant frequency-selective circuits. Quartz crystal oscillator, nekuda kwekudzikama kwema frequency, inoita basa rakakosha mumidziyo yakawanda, kusanganisira yakajairwa frequency jenareta, pulse counters, uye quartz wachi.
2. Quartz Crystal Microbalance
Quartz Crystal Microbalance (QCM) chiridzwa chinoshandisa piezoelectric mhedzisiro yequartz crystal kuyera shanduko mu electrode surface mass. Kubva payakaunzwa mukutanga kwema1960, yave chishandiso chine simba chekuona nanogram{2}level mass nekuda kwekunzwa kwayo kwakanyanya. Nheyo yaro yekushanda ndeyekuti shanduko muhuwandu hwepamusoro hwequartz crystal electrode ichashandurwa kuita frequency shanduko yeinobuda magetsi chiratidzo cheiyo oscillation circuit. Maitirwo aya anozoongororwa nemichina yekubatsira yakaita semakomputa kuti uwane-mibairo yekuyera nemazvo. Naizvozvo, iyo quartz crystal microbalance inoita basa rakakosha munzvimbo dzakawanda dzakadai semushonga, indasitiri yemakemikari, chikafu, biomedicine, kutarisa kwezvakatipoteredza, indasitiri nemauto.
3. Piezoelectric biosensor
(1) Piezoelectric immunosensor
Nheyo yekushanda yepiezoelectric immunosensor ndeyekugadzirisa masoja ekudzivirira chirwere kana maantigen pamusoro pekristaro yequartz uye kushandisa chaiyo affinity reaction pakati peantigen neantibody. Kana iyo antigen kana antibody ichayerwa yapindirana neyakagadziriswa inozivikanwa chinhu uye inogadzira chaiyo adsorption, huremu hwepamusoro hwekristaro hunozowedzera zvinoenderana. Shanduko iyi inogona kutariswa neiyo frequency shanduko ye sensor, nekudaro ichitarisa huwandu hwe adsorbed antibody kana antigen.
(2) Piezoelectric gene sensor
Musimboti wepiezoelectric gene sensor yekuona DNA ndeyekugadzirisa imwe-stranded DNA probe panzvimbo yecrystal. Kana kutevedzana kweDNA kuchaonekwa kuchienderana kwairi, hybridization reaction inoitika pachip kuumba DNA yakapetwa kaviri-yakasungwa. Iyi nzira inotungamira mukuwedzera kwekristaro misa uye shanduko yepasi viscoelasticity. Idzi shanduko dzinogona kuyerwa ne frequency shanduko ye sensor uye network kuongororwa.
