Superelastic oxide micropillars enabled by surface tension-modulated 90{degrees} domain switching with excellent fatigue resistance [Applied Physical Sciences]

Superelastic materials capable of recovering large nonlinear strains are ideal for a variety of applications in morphing structures, reconfigurable systems, and robots. However, making oxide materials superelastic has been a long-standing challenge due to their intrinsic brittleness. Here, we fabricate ferroelectric BaTiO3 (BTO) micropillars that not only are superelastic but...
