Kev taw qhia electrostrictive
Kev Siv Hluav Taws Xob Muaj qee cov khoom siv polycrystalline, xws li cov hlau lead zirconate titanate ceramics, tau tsim kho cov pawg molecular, thiaj li hu ua hluav taws xob, uas muaj qee qhov sib ncawg, thiab qhov ntev raws cov kev coj ua polarization feem ntau sib txawv los ntawm lwm cov lus qhia. Thaum ib daim teb hluav taws xob sab nraud thov, qhov hluav taws xob sau no yuav tig ua nws txoj kev coj ua kom ntau li ntau tau raws li qhov kev coj ua ntawm cov hluav taws xob sab nraud. Yog li ntawd, qhov ntev ntawm cov khoom siv no raws cov kev taw qhia ntawm lub qhov hluav taws xob sab nraud yuav hloov. Qhov tshwm sim no yog hu ua hluav taws xob Ua los ntawm lub ntsej muag tsom iav.
