Spectral validity and spindle detection of wearable frontal Electroencephalography: A per‐subject calibration framework and systematic validation against polysomnography using the Wearanize+ dataset

Sleep Research, EarlyView.
Abstract Background Wearable Electroencephalography (EEG) devices enable home sleep monitoring but require systematic spectral validation before their physiological outputs can serve as proxies for polysomnographic features. Aims This study provides comprehensive spectral validation of the Zmax EEG headband against concurrent polysomnography (PSG ...

Perforation Enhances Sound Insulation in Plate Lattice Metamaterials

Small, EarlyView.
Herein, perforations are engineered into face‐centered cubic plate lattice metamaterials to convert normally detrimental openings into acoustically active features. Experiments, finite‐element analyses, and a reduced‐order transfer‐matrix model show that selected perforation geometries activate Helmholtz‐like and cavity‐mediated resonances, enhancing ...

Crystallinity Effects on Near‐Infrared Photoresponse in Y6‐Based Organic Phototransistors

Small, EarlyView.
Solution‐processed Y6 thin films are investigated as active layers of organic field‐effect transistors and as near‐infrared photodetectors. Enhanced crystallinity in Y6 films induced by thermal annealing leads to improved charge transport and pronounced photoresponsivity.

Scalable Room‐Temperature Terahertz Graphene Cameras

Small Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...
