一种由柔性太阳能电池供电的可穿戴式汗液传感器可以连续收集多模态物理化学数据——葡萄糖、pH值、钠离子、出汗率和皮肤温度——在室内和室外的身体活动中持续超过12小时。可穿戴式汗液传感器可以潜在地用于连续和非侵入性地监测包含与疾病诊断和健康跟踪相关信息的物理化学生物标志物。然而，这种自主传感器的发展面临着许多挑战，包括实现连续和长时间监测的稳定汗液提取，以及解决多功能和复杂分析的高功率需求。在这里，我们报告了一种自主可穿戴生物传感器，它由钙钛矿太阳能电池供电，可以提供连续和无创的代谢监测。该器件采用柔性准二维钙钛矿太阳能电池组件，在室内外光照条件下均能提供充足的功率（室内光照下功率转换效率超过31%）。我们表明，可穿戴设备可以连续收集室内和室外身体活动的多模态物理化学数据-葡萄糖，pH值，钠离子，出汗率和皮肤温度超过12小时。
A wearable sweat sensor powered by a flexible solar cell can continuously collect multimodal physicochemical data-glucose, pH, sodium ion, sweat rate and skin temperature-across indoor and outdoor physical activities for over 12 h.Wearable sweat sensors can potentially be used to continuously and non-invasively monitor physicochemical biomarkers that contain information related to disease diagnostics and fitness tracking. However, the development of such autonomous sensors faces a number of challenges including achieving steady sweat extraction for continuous and prolonged monitoring and addressing the high power demands of multifunctional and complex analysis. Here we report an autonomous wearable biosensor that is powered by a perovskite solar cell and can provide continuous and non-invasive metabolic monitoring. The device uses a flexible quasi-two-dimensional perovskite solar cell module that provides ample power under outdoor and indoor illumination conditions (power conversion efficiency exceeding 31% under indoor light illumination). We show that the wearable device can continuously collect multimodal physicochemical data-glucose, pH, sodium ion, sweat rate and skin temperature-across indoor and outdoor physical activities for over 12 h.
