Flexible wearable electronics for cardiovascular monitoring from surface signals to deep physiological insights

open access: yesFlexMat, EarlyView.
This review organizes flexible wearable electronics for cardiovascular monitoring into four interconnected information layers: surface electrophysiology, hemodynamic sensing, vascular imaging, and biofluid biomarker analysis. This framework clarifies how electrical rhythm, vascular loading, structural and flow‐related features, and biochemical states ...

Aerogel Fiber: A One‐Dimensional Programmable Porous Matter for Next Thermal Management Materials

open access: yesInterdisciplinary Materials, EarlyView.
Aerogel fibers are redefined as one‐dimensional programmable porous matter, where thermal transport is governed by multiscale pathway engineering. By reconstructing and decoupling transport pathways from molecular to textile scales, these systems integrate insulation, radiative cooling, and adaptive thermal regulation.
