ʻO nā kristal Quartz, ma muli o kā lākou hopena piezoelectric kūʻokoʻa, pāʻani i kahi hana koʻikoʻi i nā kula he nui. ʻO kā lākou mau noi e pili ana i nā ʻāpana -ʻenehana kiʻekiʻe, me nā mea uila, kamaʻilio, a me ka aerospace.
1.Quartz Crystal Oscillators
Hoʻohana ka oscillator quartz crystal i ka quartz crystal ma ke ʻano he kumu o ka alapine resonant -kaapuni koho. Hana ʻia kēia oscillator ma ka ʻoki pono ʻana i ke aniani quartz i loko o nā ʻāpana lahilahi a hoʻopili i nā papa metala i ko lākou mau ʻili. Hoʻokumu ʻia kāna kumu hana ma ka hopena piezoelectric inverse: quartz crystals vibrate mechanically ma lalo o ka mana o ke kahua uila. No ka mea, loaʻa i kēlā me kēia aniani quartz kahi alapine haʻalulu kūlohelohe maoli, hiki ke resonance i ka wā e hoʻopili ai ke kahua uila i kēia alapine. ʻO kēia hiʻohiʻona ka mea i koho maikaʻi ʻia nā kristal quartz no nā kaapuni koho kiʻekiʻe-ka ʻO ka Quartz crystal oscillators, ma muli o ko lākou paʻa pinepine ʻana, ke pāʻani nei i kahi kuleana nui i nā mea hana he nui, me nā mea hana alapine maʻamau, nā helu pulse, a me nā uaki quartz.
2. Quartz Crystal Microbalance
ʻO ka Quartz Crystal Microbalance (QCM) kahi mea hana e hoʻohana i ka hopena piezoelectric o ke aniani quartz e ana i nā loli i ka nui o ka ʻili electrode. Mai kona hoʻomaka ʻana i ka makahiki 1960, ua lilo ia i mea hana ikaika no ka ʻike maka nui ʻana o ka nanogram-ma muli o kona ʻano kiʻekiʻe loa. ʻO kāna kumu hana, ʻo ka hoʻololi ʻana i ka nui o ka ʻili o ka quartz crystal electrode e hoʻololi ʻia i hoʻololi pinepine o ka hōʻailona uila puka o ke kaapuni oscillation. Hoʻopili ʻia kēia kaʻina hana e nā mea kōkua e like me nā kamepiula no ka loaʻa ʻana o nā hualoaʻa ana pololei kiʻekiʻe. No laila, he hana koʻikoʻi ka quartz crystal microbalance i nā kula he nui e like me ka lāʻau lapaʻau, ʻoihana kemika, meaʻai, biomedicine, ka nānā ʻana i ke kaiapuni, ʻoihana a me ka pūʻali koa.
3. Piezoelectric biosensor
(1) Piezoelectric immunosensor
ʻO ke kumu hana o ka piezoelectric immunosensor ka hoʻoponopono ʻana i nā antibodies a i ʻole antigens ma ka ʻili o ka quartz crystal a hoʻohana i ka hopena pili pono ma waena o ka antigen a me ka antibody. Ke hoʻopili ʻia ka antigen a i ʻole ka antibody e ana ʻia me ka mea ʻike paʻa a hoʻopuka i kahi adsorption kikoʻī, e piʻi aʻe ka ukana nui o ke aniani. Hiki ke nānā ʻia kēia hoʻololi e ka hoʻololi pinepine o ka sensor, a laila e hoʻoholo ai i ka nui o ka adsorbed antibody a i ʻole antigen.
(2) Piezoelectric gene sensor
ʻO ke kumu kumu o ka mea ʻike gene piezoelectric no ka ʻike ʻana i ka DNA ʻo ia ka hoʻoponopono ʻana i ka -paʻa DNA ma ka ʻili aniani. Ke hoʻohui ʻia ke kaʻina DNA e ʻike ʻia me ia, hiki mai ka hopena hybridization ma ka chip e hana i ka DNA stranded -lua. ʻO kēia kaʻina hana e alakaʻi i ka hoʻonui ʻana i ka nui o ka kristal a me nā loli i ka viscoelasticity o ka ʻili. Hiki ke ana ʻia kēia mau hoʻololi e ka hoʻololi pinepine ʻana o ka ʻike a me ka ʻike pūnaewele.
