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.

Implantable Biophotonic Device for Wirelessly Cancer Real‐Time Monitoring and Modulable Treatment

open access: yesAdvanced Science, EarlyView.
A wirelessly implantable biophotonic device is capable of distinguishing tumors and evaluating their progression by monitoring sO2 levels indicative of the tumor hypoxic microenvironment. Additionally, this device is not only employed for in situ PDT but also for concurrent monitoring of chemotherapy and PDT progress, thereby enabling the evaluation ...
