Cov nyhuv Piezoelectric
Thaum qee qhov dielectrics tau deformed los ntawm sab nraud quab yuam hauv ib qho kev taw qhia, polarization yuav tshwm sim sab hauv lawv, thiab tib lub sijhawm, cov nqi zoo thiab tsis zoo yuav tshwm sim rau nws ob sab ntsej muag. Thaum lub zog sab nraud raug tshem tawm, nws yuav rov qab mus rau lub xeev tsis ceev. Qhov tshwm sim no hu ua qhov zoo piezoelectric effect.
