We report a nonenzymatic wearable sensor for electrochemical analysis of perspiration glucose. Multipotential steps are applied on a Au electrode, including a high negative pretreatment potential step for proton reduction which produces a localized alkaline condition, a moderate potential step for electrocatalytic oxidation of glucose under the alkaline condition, and a positive potential step to clean and reactivate the electrode surface for the next detection. Fluorocarbon-based materials were coated on the Au electrode for improving the selectivity and robustness of the sensor. A fully integrated wristband is developed for continuous real-time monitoring of perspiration glucose during physical activities, and uploading the test result to a smartphone app via Bluetooth.

非酶可穿戴传感器,用于汗液葡萄糖的电化学分析
我们报告了一种用于汗液葡萄糖电化学分析的非酶可穿戴传感器。多电位步骤应用于Au电极上,包括用于产生质子碱性条件的质子还原的高负预处理电位步骤,用于在碱性条件下对葡萄糖进行电催化氧化的中等电位步骤以及用于清洁和重新活化葡萄糖的正电位步骤。电极表面,用于下一次检测。将基于碳氟化合物的材料涂覆在Au电极上,以提高传感器的选择性和坚固性。开发了一个完全集成的腕带,用于在体育活动期间连续实时监测汗液中的葡萄糖,并将测试结果通过蓝牙上传到智能手机应用程序。
