A Generative AI‐Assisted Piezo‐MEMS Ultrasound Device for Plant Dehydration Monitoring

Advanced Science, EarlyView.
This study introduces a complementary metal–oxide–semiconductor (CMOS)‐compatible wearable piezoelectric micromachined ultrasound transducers (PMUTs) that sandwiches the leaf (PMUT–Leaf–PMUT, PLP) and employs generative artificial intelligence for real‐time analysis.

A Self‐Adaptive Reconfigurable Metasurface for Electromagnetic Wave Sensing and Dynamic Reflection Control

Advanced Science, EarlyView.
Reconfigurable metasurfaces typically require human intervention or complex, resource‐heavy processes. This innovative self‐adaptive metasurface senses an incident wave's direction, adjusting reflection in real‐time using a simple electronics module. It eliminates external controllers, reducing response time, energy consumption, and costs. Applications

Quantum Geometric Engineering of Dual Hall Effects in 2D Antiferromagnetic Bilayers via Interlayer Magnetic Coupling

Advanced Science, EarlyView.
Precise tuning of interlayer magnetic coupling in two‐dimensional bilayers enables control over altermagnetic and PT‐symmetric antiferromagnetic phases. This dual‐phase platform yields two intrinsic Hall responses: a Berry curvature–driven linear anomalous Hall effect and a quantum metric–induced second‐order nonlinear anomalous Hall effect ...
