Precise Cell Type Electrical Stimulation Therapy Via Force‐electric Hydrogel Microspheres for Cartilage Healing (Adv. Mater. 7/2025)

Force-Electric Hydrogel Microspheres The integration of barium titanate (BaTiO3) piezoelectric nanoparticles with microfluidic HAMA hydrogel microspheres enables sustained and stable electrical signal output under wireless ultrasound modulation, precisely regulating cellular fate at the micron scale. By incorporating peptides that specifically recruit target cell populations, this novel piezoelectric hydrogel microsphere system effectively addresses the heterogeneity issues of traditional electrical stimulation therapies, providing a promising and translatable approach for promoting cartilage repair.
