介绍了一种用于人体汗液中微量金属无创监测的可穿戴式电化学传感器。基于临时纹身的可印刷剥离伏安传感器已被应用于在身体活动期间使用铋/Nafion膜电极实时监测汗液中的锌。锌临时纹身传感器可承受重复机械应力，并在身体测试期间显示明确的锌响应。这种非侵入性的溶出伏安检测可以很容易地扩展到其他相关的重金属的表皮测量。(C)2014爱思唯尔有限公司版权所有。
A wearable electrochemical sensor for non-invasive monitoring of trace metals in human perspiration is described. The temporary tattoo-based printable stripping-voltammetric sensor has been applied for real-time monitoring of zinc in sweat using a bismuth/Nafion film electrode during physical activity. The Zn temporary tattoo sensor withstands repeated mechanical stress and displays a well-defined Zn response during on-body testing. Such a non-invasive stripping-voltammetric detection could be readily expanded to epidermal measurements of other relevant heavy metals. (C) 2014 Elsevier B.V. All rights reserved.
