direct piezoelectric effect meaning in Hindi

Examples

1. where the first term corresponds to the direct piezoelectric effect and the second term corresponds to the flexoelectric polarization induced by the strain gradient.
2. Here, the flexoelectric coefficient, \ mu _ { ijkl }, is a fourth-rank polar tensor and d _ { ijk } is the coefficient corresponding to the direct piezoelectric effect.
3. The reversible process in that materials exhibiting the direct piezoelectric effect ( the internal generation of electrical charge resulting from an applied mechanical force ) also exhibit the reverse piezoelectric effect ( the internal generation of a mechanical strain resulting from an applied electrical field ).
