Which statement correctly describes piezoelectric transducers (PZT) versus electrostrictive transducers?

• A. Electrostrictive materials rely on quadratic effects and can offer higher temperature stability or different bandwidth behaviors but are less common.
• B. Piezoelectric transducers use linear electric-field-induced strain with high coupling.
• C. Piezoelectric transducers rely on piezoelectric coupling with magnetic fields.
• D. Electrostrictive transducers are more common than piezoelectric.

Answer: (B)
