Large Electromechanical Response and Field-Induced Shape Memory Effect in Ferroelectric Ceramics. [PDF]

Adv Sci (Weinh)
A large asymmetry field‐induced deformation (2.77%) and shape memory effect (1.75%) have been found in (1‐x)(75Na0.5Bi0.5TiO3‐25SrTiO3)‐xPbTiO3. Because of the electron injection, the two sides of ceramics are in different polarization state and generate a bending deformation over the ceramic.
