Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Arbitrary Total Angular Momentum Vectorial Holography Using Bi‐Layer Metasurfaces

Advanced Materials, EarlyView.
A bi‐layer metasurface platform is presented for arbitrary total angular momentum vectorial holography, where polarization and orbital angular momentum are exploited as independent multiplexing dimensions. By overcoming symmetry limitations of single‐layer designs, the approach generates distinct vectorial holographic images for each orthogonal TAM ...

A State‐Adaptive Koopman Control Framework for Real‐Time Deformable Tool Manipulation in Robotic Environmental Swabbing

Advanced Robotics Research, EarlyView.
This work presents a state‐adaptive Koopman linear quadratic regulator framework for real‐time manipulation of a deformable swab tool in robotic environmental sampling. By combining Koopman linearization, tactile sensing, and centroid‐based force regulation, the system maintains stable contact forces and high coverage across flat and inclined surfaces.
