Cov lus txhais ntawm cov nyhuv piezoelectric
Thaum qee lub muaju tau deformed los ntawm sab nraud quab yuam, polarization yuav tshwm sim, sib sau cov lej sib txawv ntawm cov nqi tsub rau sab nraud, hu ua cov nyhuv piezoelectric. Muaj ntau hom piezoelectric muaju, feem ntau yog quartz, potassium sodium tartrate (Rochelle ntsev), potassium dihydrogen phosphate (KDP), ammonium dihydrogen phosphate (ADP), barium titanate, thiab semiconductors xws li gallium arsenide thiab zinc sulfide Thiab piezoelectric ceramics. Cov neeg siv tshuab kev co ntawm piezoelectric muaju tuaj yeem hloov mus rau hluav taws xob kev ua kom muaj zog. Nws nquag siv los tsim cov siv lead ua oscillators. Nws cov txiaj ntsig zoo tshaj yog qhov siab ruaj khov ntawm cov zaus oscillation. Nws tuaj yeem siv los tswj kev ceev cov zaus ntawm kev ua dej khov hauv cov xov tooj cua thev naus laus zis. Hom oscillator no tau siv dav Quartz moos. Piezoelectric muaju kuj tseem siv nyob rau hauv cov khoom siv electroacoustic xws li microphones thiab phono cartridges. Cov txheej txheem piezoelectric tuaj yeem siv los ntsuas kev ntsuas siab, kev co thiab nrawm hauv ntau qhov xwm txheej.
