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 ...

Triboelectric nanogenerators for vehicle intelligent cockpits

open access: yesFlexMat, EarlyView.
Converting mechanical stimuli from drivers and vehicle motion into electrical signals, triboelectric nanogenerators provide promising interfaces toward passive, flexible, distributed and intelligent sensing for next‐generation automotive cockpits to support three core functional dimensions: driver state monitoring, vehicle state monitoring, and human ...

Flexible lithium‐ion batteries: Materials design, interfacial regulation, and strain‐adaptive device architectures

open access: yesFlexMat, EarlyView.
This review highlights recent advances in flexible lithium‐ion batteries for wearable and deformable electronics. It systematically examines deformable electrodes, mechanically compliant gel and solid‐state electrolytes, and strain‐adaptive cell architectures, alongside an analysis of mechano‐electrochemical coupling under dynamic deformation.

Zinc oxide/polydimethylsiloxane‐coated carbon fiber yarns for machine‐learning‐assisted gait classification

open access: yesInfoScience, EarlyView.
Gait analysis can provide valuable information for identifying changes in movement associated with neurological disorders, thus serving as an important support tool in several areas, including healthcare and rehabilitation. In this study, zinc oxide/polydimethylsiloxane (ZnO/PDMS)‐coated carbon fiber yarns were developed and evaluated as pressure ...

Local‐distortion regulation of small‐polaron transport: A design degree of freedom for thermoelectric oxides

open access: yesInfoMat, EarlyView.
The thermoelectric performance of oxides is closely linked to how small polarons move through a locally distorted crystal lattice. Here, we compare Ce‐ and La‐doped CaMnO3 with comparable carrier concentrations but distinctly different local distortion backgrounds, showing that stronger distortion more strongly traps small polarons and delays their ...

High‐Efficiency Graphene‐Silicon Slot‐Waveguide Microring Modulator at 1.5 and 2 µm Wavelength Bands

open access: yesLaser &Photonics Reviews, EarlyView.
E/O modulators typically face a trade‐off between bandwidth and modulation efficiency. An integrated E/O modulator is presented that simultaneously achieves wideband, large bandwidth, and high modulation efficiency operation by embedding a partially overlapped double‐layer graphene on a compact silicon slot‐waveguide microring resonator.
