A Comparative Analysis of Plasmonic and Dielectric Metasurface Sensing Platforms Powered by Bound States in the Continuum

open access: yesAdvanced Functional Materials, EarlyView.
This work reveals a fundamental trade‐off between plasmonic and dielectric metasurfaces for molecular sensing. A clear performance crossover is identified: dielectric metasurfaces excel in air, while plasmonic metasurfaces dominate in lossy solvents. These results establish design rules for infrared metasurface sensors and enable optimized performance ...

Soft Magnetic Artificial Muscles with High Work Density and Actuation Strain via Dual Cross‐Linking Design

open access: yesAdvanced Functional Materials, EarlyView.
A high‐performance magnetic composite actuator that integrates covalent and reversible physical cross‐links within a stiffness‐tunable polymer matrix embedded with functionalized magnetic particles is presented. The actuator exhibits programmable magnetic responsiveness, a stiffness switching ratio of 1.37 × 103, stretchability up to 1274%, large ...

Strain‐Activated Photo‐Dehalogenation Unlocks Low‐Energy One and Two‐Photon 3D Microfabrication

open access: yesAdvanced Functional Materials, EarlyView.
5,14‐NMI‐Cz acts, conversely to its 7,10‐NMI‐Cz(7,10‐'dibromo‐2‐(2,6‐diisopropylphenyl)‐1H‐benzo[lmn]carbazolo[9,1‐bc][2,8]phenanthroline‐1,3(2H)‐dione) counterpart, as modular photoinitiator with panchromatic photoactivity, featuring a weak C–Br bond from geometric strain for efficient Type I & II initiation. These studies demonstrate applicability of

Reconfigurable Metamirrors Based on Compliant Mechanisms

open access: yesAdvanced Functional Materials, EarlyView.
Providing the basis for numerous practical applications, the reconfigurability of metadevices is of great importance. Through the integration of controlled mechanical deformation with chiral meta‐atoms, a compliant mechanism based metamirror is demonstrated for active control over the polarization of electromagnetic waves.

Magnetic Unclonable Functions Leveraging Remanence and Anhysteretic States

open access: yesAdvanced Functional Materials, EarlyView.
A micrometric array of magnetic pillars provides a stable and unclonable hardware for generating cryptographic keys. From a single device, the ability is demonstrated to produce a 470‐bit key while also offering a reconfigurable mode of operation.
