Flexible ferroelectrics High-quality ferroelectric materials, which polarize in response to an electric field, are usually oxides that crack when bent. Dong et al. found high-quality membranes of barium titanate surprisingly flexible and super-elastic. These films accommodate large strains through dynamic evolution nanodomains during deformation. This discovery is important for developing more robust devices. Science , this issue p. 475
