Biocompatible Magnetopyroelectric Composite Films for Cell Stimulation
Advanced Science, EarlyView.Magnetopyroelectric films couple Fe3O4 nanoparticles with pyroelectric P(VDF‐TrFE) to turn alternating magnetic fields into controlled heat and pyroelectric currents. This heavy‐metal free platform safely boosts neural progenitor cells differentiation via synergistic thermal and pyroelectrical cues, engages AKT and calcium pathways, and opens practical
