← ScienceWhich outcome occurs when a crystalline piezoelectric sensor is mechanically stressed?
A)Electric potential generation occurs steadily✓
B)Heat accumulates throughout the structure
C)Optical transparency briefly decreases
D)Acoustic impedance approaches zero
💡 Explanation
A mechanical stress causes the piezoelectric effect, because a dipole polarization emerges due to crystal lattice deformation, therefore an electric potential is generated, rather than only heat from friction or transparency changes related to other optical phenomena.
