A Dual‐Modal Wearable Pulse Detection System Integrated with Deep Learning for High‐Accuracy and Low‐Power Sleep Apnea Monitoring

open access: yesAdvanced Science, EarlyView.
A dual‐modal wearable pulse detection system is developed for sleep apnea monitoring by integrating a self‐powered PENG and PPG sensor with a biomimetic fingertip structure. Through a two‐stage detection strategy, continuous PPW monitoring and on‐demand PPG detection achieve high‐accuracy sleep apnea recognition while maintaining low power consumption.

Polarization‐Controlled Transmissive Plasmonic Color Filter Using a Dimer‐Aperture Array

open access: yesAdvanced Science, EarlyView.
An aluminum dimer aperture array plasmonic metasurface is proposed and fabricated to achieve efficient polarization‐color filtering with CMOS‐compatible materials. The structure's simultaneous polarization‐color filtering capability is shown using structural color generation, where color gamut coverage of 76% and extinction ratio over 20 is achieved ...

Achromatic 3D Multi‐Color Orbital Angular Momentum Holography

open access: yesAdvanced Science, EarlyView.
This work presents an achromatic 3D multicolor orbital angular momentum (OAM) holography based on spatial multiplexing. By integrating wavelength‐specific lens functions onto monochromatic Fourier OAM‐dependent holograms and high‐resolution spatial discretization and interleaving via two‐photon lithography (TPL), the approach addresses axial chromatic ...
