Acoustic Impedance‐Tailored High‐Performance Ultrasound‐Driven Triboelectric Nanogenerators

Advanced Energy Materials, EarlyView.
An acoustic impedance–mismatched triboelectric nanogenerator is presented for efficient ultrasound energy harvesting in implantable medical devices. Concave and convex membrane patterning induces controlled acoustic impedance mismatch, which boosts output by ∼200% and ensures stable operation over 100 million cycles and six weeks in vivo, highlighting ...

Enhanced Lattice Polarization and Directed Charge Transport Toward Pt Surface Sites Accelerate the Volmer Step in Piezocatalytic H2 Evolution on Co‐Doped BiFeO3

Advanced Energy Materials, EarlyView.
We report a Pt‐decorated Co‐doped BiFeO3 (Pt/BCFO) piezocatalyst achieving an H2 evolution rate of 1896.4 µmol g−1 h−1. Co‐doping induces lattice distortion, enhancing piezoelectric polarization, while Pt sites promote water dissociation. Embedded in a poly(vinylidene fluoride) matrix, Pt/BCFO enables efficient mechanical energy harvesting and catalyst
