Vertically Aligned Carbon Nanotube Mechano‐Electrochemical Generator for Ultralow‐Frequency Ocean Wave Monitoring

open access: yesAdvanced Science, EarlyView.
A mechano‐electrochemical generator is proposed that harvests energy from ultralow‐frequency waves below 0.01 Hz for self‐powered disaster monitoring. The generator minimizes signal distortion, enabling precise measurement of subtle waves with overlapping frequencies.

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 ...

Moisture Harvesting by the Structure Regulation of Hygroscopic Hydrogel for Energy and Water Sustainability

open access: yesAdvanced Electronic Materials, EarlyView.
Hygroscopic hydrogels are capable of utilizing the moisture from air, which can transfer the gaseous water to liquid by a surface phase transition. Taking advantage of this water, sustainable water production, thermal management, and electricity generation can be realized.
