Flexoelectricity in Ceramics and Their Application /

Flexoelectricity is the ability of materials to generate a voltage when they are bent or, conversely, to bend under voltage. Flexoelectricity can be present in all materials; however, the magnitude of the flexoelectric coefficients is so small that flexoelectricity is virtually imperceptible on the...
