Sweat monitoring offers non-invasive, dynamic, and sustainable technological advantages, facilitating the rapid development of personalized healthcare and precision health management systems. However, efficient sweat collection and rapid screening detection remain highly challenging due to the low secretion rate and rapid evaporation of sweat. Inspired by the sophisticated heterogeneous wettability distribution on cicada wing surfaces, the research group proposed a self-assembly strategy based on laser-cut water interfaces, developing a cellulose triboelectric material with heterogeneous wettability. Driven by the coupling effects of wettability gradients and Laplace pressure differences, sweat is rapidly transported from the material’s edges to the central region, effectively enriching target metabolites and thereby enhancing the sensing signal-to-noise ratio beyond that of mainstream sweat sensors. By integrating ion-selective permeable membranes and data processing modules, a portable wearable patch was constructed, enabling salt ion screening and remote wireless monitoring capabilities.

In recent years, the “Advanced Wood Fiber Materials” research team has conducted in-depth exploration into the development and advanced applications of cellulose triboelectric materials, achieving a series of original research outcomes in related fields. Their findings have been published in prestigious international academic journals such as Nature Communications, Advanced Materials, and Matter.
