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 ...

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.

Advanced Photonics Research, EarlyView.Electron acceleration using multipetawatt femtosecond lasers and subcritical density plasmas achieves a maximum charge of 245 nC, with an injection rate of up to 100 nC per picosecond. The charge variation with plasma density, initially increasing and then decreasing, arises from the competition between the injection of multiple plasma waves and laser ...
