In‐Wheel Piezoelectric DC Power Generator With Zero Resistive Torque

Advanced Science, EarlyView.
In this paper, we present a wheel‐shaped direct‐current piezoelectric generator (DC‐PG) that fundamentally overcomes these constraints by producing phase‐stable DC electricity directly from rolling motion. By embedding this system into suitcase wheels, we demonstrated a fully integrated real‐time location tracking system powered solely by mechanical ...

Reprogrammable Phase‐Transition Composites for Adaptive Dynamic Shape Morphing

Advanced Science, EarlyView.
This paper reports a bio‐inspired reprogrammable phase‐transition composites that uses the stiffness change induced by reversible solid‐liquid phase transition to program and regulate the material deformation actuated by reversible liquid‐vapor phase transition, thereby achieving adaptive dynamic deformation in a controllable manner, and enabling ...

Broadband Achromatic Programmable Electromagnetic Camouflage via Fluidic‐Accessible Metasurface

Advanced Science, EarlyView.
A fluidic access metasurface enables dynamic, broadband electromagnetic illusions. By physically reconstructing conductive patterns with liquid metal, the metasurface achieves real‐time, pixel‐level control over phase dispersion. This allows for the programmable generation of arbitrary strong scattering point arrays, effectively deceiving high ...

Large‐Scale Synthesis of Monodispersed Perovskite Nanocrystals via Autonomous Continuous Droplet Microfluidics

Advanced Science, EarlyView.
In this work, we propose a novel on‐chip microscale continuous droplet‐in‐flow synthesis (μ‐CDFS) that utilizes zwitterionic ligands to enable large‐scale preparation of perovskite nanocrystals (PNCs) with high emission efficiency and monodispersity.
