Owing to advantages of miniaturization, convenient integration, flexibility, and real-time monitoring, wearable smartsensors have received numerous attention and greatly developed in various fields. However, there usually appears a contradiction between sensing behaviors and simple fabricated methods, seriously limiting on-site detection of actual samples. In this work, a porous Au-based smartsensor has been in situ prepared by combining screen printing technology and sacrificial template electrodeposition. Thanks to abundant active adsorption sites, multiple metal ions (Pb, Cu, and Hg) can be easily achieved on-site detection by this smart platform with a low limit of detection as well as high sensitivity, excellent selectivity, good stability, repeatability, and bending performance. Significantly, it also exhibits a reliable detective capability in actual liquid cosmetic samples with a portable cellphone, which identically corresponds to standard inductively coupled plasma-mass spectrometry (ICP--MS) evaluation. Therefore, this wearable smartsensor provides a promising platform for artificial intelligence application in future daily life.
由于具有小型化、便于集成、灵活性和实时监测等优点，可穿戴智能传感器受到了广泛关注，并在各个领域得到了极大的发展。然而，传感行为与简单的制造方法之间通常存在矛盾，严重限制了实际样品的现场检测。在这项工作中，通过结合丝网印刷技术和牺牲模板电沉积原位制备了一种多孔金基智能传感器。由于具有丰富的活性吸附位点，该智能平台能够以低检测限、高灵敏度、优异的选择性、良好的稳定性、重复性和弯曲性能轻松实现多种金属离子（铅、铜和汞）的现场检测。值得注意的是，它还通过便携式手机在实际液体化妆品样品中表现出可靠的检测能力，这与标准电感耦合等离子体质谱（ICP-MS）评估结果完全一致。因此，这种可穿戴智能传感器为未来日常生活中的人工智能应用提供了一个有前景的平台。
