Kristal Quartz, n'ihi mmetụta piezoelectric ha pụrụ iche, na-arụ ọrụ dị mkpa n'ọtụtụ mpaghara. Ngwa ha gbasara ọtụtụ ngalaba teknụzụ dị elu, gụnyere ngwa eletrọnịkị, nkwukọrịta na ikuku ikuku.
1.Quartz Crystal Oscillators
Oscillator quartz kristal na-eji kristal quartz dị ka isi nke ugboro resonant - sekit ahọpụtara. A na-arụ oscillator a site n'ibibi kristal quartz n'ụzọ ziri ezi n'ime mpekere dị mkpa na itinye efere ígwè n'elu ha. Ụkpụrụ ọrụ ya dabere na mmetụta piezoelectric nke na-agbanwe agbanwe: kristal quartz na-ama jijiji n'ụzọ nke igwe n'okpuru mmetụta nke mpaghara eletrik ọzọ. N'ihi na kristal quartz ọ bụla nwere oge ịma jijiji ebumpụta ụwa, resonance na-apụta mgbe igwe eletrik etinyere dabara na ugboro a. Njirimara a na-eme kristal quartz ka ọ bụrụ nhọrọ dị mma maka ọtụtụ sekit ahọpụtara{{5}ezigbo resonant ugboro-. Quartz kristal oscillators, n'ihi nkwụsi ike ugboro ole ha dị mma, na-arụ ọrụ dị mkpa n'ọtụtụ ngwaọrụ, gụnyere ndị na-emepụta ihe na-emepụta ugboro ugboro, pulse counters, na quartz clocks.
2. Quartz Crystal Microbalance
Quartz Crystal Microbalance (QCM) bụ ngwá ọrụ na-eji piezoelectric mmetụta nke quartz crystal tụọ mgbanwe na electrode elu uka. Kemgbe iwebata ya na mmalite 1960s, ọ ghọwo ngwa ọrụ siri ike maka nchọpụta nanogram{2}}ọkwa n'ihi oke mmetụta ya. Ụkpụrụ ọrụ ya bụ na a ga-agbanwe mgbanwe nke elu elu nke quartz crystal electrode ka ọ bụrụ mgbanwe ugboro ugboro nke mgbaàmà eletrik nke mmepụta nke sekit oscillation. A na-enyocha usoro a site na ngwa inyeaka dịka kọmpụta iji nweta nsonaazụ nha dị elu-. Ya mere, microbalance quartz crystal na-arụ ọrụ dị mkpa n'ọtụtụ mpaghara dị ka ọgwụ, ụlọ ọrụ kemịkalụ, nri, biomedicine, nlekota gburugburu ebe obibi, ụlọ ọrụ na ndị agha.
3. Piezoelectric biosensor
(1) immunosensor piezoelectric
Ụkpụrụ ọrụ nke piezoelectric immunosensor bụ iji dozie ọgwụ mgbochi ma ọ bụ antigens n'elu kristal quartz ma jiri mmeghachi omume mmekọrịta dị n'etiti antigen na antibody. Mgbe antigen ma ọ bụ mgbochi a ga-atụ na-emekọrịta ihe na ihe a na-ahụ anya nke ọma wee mepụta mgbasa ozi akọwapụtara, oke elu nke kristal ga-abawanye otu ahụ. Enwere ike nyochaa mgbanwe a site na mgbanwe mgbanwe nke ihe mmetụta ugboro ugboro, si otú a na-achọpụta ọnụọgụ antibody ma ọ bụ antigen adsorbed.
(2) Piezoelectric gene sensọ
Ụkpụrụ bụ isi nke ihe mmetụta piezoelectric gene sensọ maka nchọpụta DNA bụ idozi otu{0}} nyocha DNA nke tọrọ n'elu kristal. Mgbe usoro DNA nke a ga-achọpụta na-akwado ya, mmeghachi omume ngwakọ na-apụta na mgbawa iji mepụta DNA gbara okpukpu abụọ-. Usoro a ga-eduga na mmụba nke kristal na mgbanwe na viscoelasticity elu. Enwere ike tụọ mgbanwe ndị a site na mgbanwe ugboro ugboro nke ihe mmetụta na nyocha netwọk.
