Recent Progress on Flexible Multimodal Sensors: Decoupling Strategies, Fabrication and Applications

open access: yesAdvanced Materials, EarlyView.
In this review, we establish a tripartite decoupling framework for flexible multimodal sensors, which elucidates the underlying principles of signal crosstalk and their solutions through material design, structural engineering, and AI algorithms. We also demonstrate its potential applications across environmental monitoring, health monitoring, human ...

Tunable Plasmonic Response of Silver Nanoparticles Entangled in Detonation Nanodiamond Network via Colloidal Self‐Assembly

open access: yesAdvanced Materials Interfaces, EarlyView.
Detonation nanodiamonds form a network that entangles silver nanoparticles into stable nanocomplexes. The structure can fine‐tune and enhance plasmonic absorption through nearfield electromagnetic interactions but prevents silver particle aggregation. The study shows how the arrangement and concentration of particles affect light absorption, offering a
