Synergistic EMI Shielding: The Role of Nanoparticle Size and Alternating Bi‐Layer Coatings in Hybrid Fabrics

Advanced Materials Technologies, EarlyView.
This study fabricates three types of hybrid knitted fabrics: AgNPs of varying sizes are synthesized on the fabric, MXene nanosheets are applied via spray coating, and alternating AgNPs/MXene bi‐layers are added. The effects of particle size, material type, and bi‐layer structure on EMI shielding (≈60 dB), as well as breathability, air permeability, and

When Cellulose Moves: Smart Sensors and Actuators

Advanced Materials Technologies, EarlyView.
This review highlights cellulose‐derived soft actuators alongside with cellulose‐based sensors. Emphasis is placed on their integration into multifunctional devices that couple sensing and actuation to mimic natural motion and adaptability. We also discuss the challenges of achieving robust, reversible, and multi‐stimuli‐responsive motion, and outline ...

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

Smart Theremin Based on Electromagnetic Metasurfaces for Fine Dual‐Hand Perception

Advanced Optical Materials, EarlyView.
The proposed Meta‐Theremin leverages a frequency‐spatial multiplexing metasurface to enable robust dual‐hand perception by shielding environmental noise and confining EM fields to interaction zones. Its physics‐informed neural network decouples hand‐specific echoes, enhancing accuracy.
