Full‐Domain 3D Digital Twin for Comprehensive Analysis and Validation of Standing Surface Acoustic Wave Generation on LiNbO3 Substrate

Advanced Materials Technologies, EarlyView.
A full‐domain 3D digital twin of a standing surface acoustic wave (SSAW) device on 128° YX LiNbO3 is developed and experimentally validated. The predictive power of the model is confirmed by electrical characterisation and laser Doppler vibrometry measurements, which show excellent agreement with simulations.

Ultrasound‐Powered, Battery‐Free Implants via Triboelectric Energy Harvesting

Advanced Materials Technologies, EarlyView.
Ultrasound‐driven triboelectric nanogenerators (US‐TENGs) present a promising approach to battery‐free implants by combining body‐safe ultrasound with the material and structural versatility of TENGs. This review categorizes current US‐TENG research into long‐term and transient short‐term applications and discusses key challenges in materials, device ...

Millisecond‐Switching Dual‐Band/Dual‐Polarization Ka‐Band Wavefront Control Enabled by a Complementary Liquid‐Crystal Metasurface

Advanced Materials Technologies, EarlyView.
An LCD‐compatible complementary liquid‐crystal metasurface delivers dual‐band, dual‐polarized Ka‐band wavefront control with millisecond switching via a 10‐µm LC gap. Interlaced patch/slot pairs enable independent phase tuning at 28 and 38 GHz, while strategic 45° slot rotation suppresses parasitic resonances. Measurements on a 160 × 160‐cell prototype

Multifunctional Conjugated Ligand with Intimate Binding Improves Luminescence, Charge Transport, and Stability in CsPbBr3 Perovskite Nanocrystals

Advanced Optical Materials, EarlyView.
A conjugated oligoelectrolyte (COE) ligand enhances the photoluminescence, stability, and charge transport properties of CsPbBr3 perovskite nanocrystals. The dicationic COE facilitates strong surface coordination and effective defect passivation, leading to improved exciton binding energy, while COE‐assisted energy funneling further boosts luminescence.
