Stretchable, Tough, and Luminescent Perovskite Molecular Ferroelectric Composite: Empowering Reliable Self-Powered Motion Sensing in High Humidity and Subzero Temperatures.

ABSTRACT: Piezoelectric materials for wearable biomechanical sensing require high flexibility, including the mechanical capacity to endure stretching and bending deformations, etc. However, existing strategies for flexible composites embedding typically brittle piezoelectric crystals into polymer matrices still suffer from limited stretchability and mechanical strength, falling short of dynamic, all-day wearable scenarios. Herein, we synthesize a new luminescent organic-inorganic hybrid perovskite ferroelectric molecular crystal, N,N-dimethylallylammonium MnCl₃ (DMAA-MnCl₃), which exhibits a transverse piezoelectric response of about 36 pC/N and a higher Curie temperature (T_c = 357 K) than that of its Cd analog (ΔT = +18 K; Wang et al.
