Abstract Fluoropolymers and metal halide perovskites (MHPs), as two classes of important piezoelectric materials, suffer from active phases through a facile process brittleness led poor manufacturability, respectively. Here, TMCM‐CdCl 3 /PVDF nanocomposites (TMCM = trimethylchloromethyl ammonium, PVDF polyvinylidene fluoride) are synthesized to overcome the above shortcomings. The abundant hydrogen (H) chlorine (Cl) sites in can interlock with H fluorine (F) atoms within via C─H···Cl C─H···F interactions. This programming effect augments dipole alignment consequently promotes formation polar PVDF. devices made by these exhibit high energy harvesting properties surpassing established MHP/PVDF analogues, prominent performance sensing delicate human motions. Moreover, show exceptional capabilities for detecting underwater ultrasound waves. signal intensity is ≈4 times that commercial film devices, frequency distortion only quarter observed ceramic transducers. study opens up new possibilities developing high‐performance creation advanced electromechanical devices.
