The development of a flexible sensing platform for potential detection of chemicals is of great importance for probing health parameters. However, the fabrication of portable flexible sensors for exogenous chemicals that are known to be harmful to human health and the environment is still a challenge. Herein we report a flexible electrochemical sensor for on-site and portable detection of the potential exogenous pollutant iodine. The sensor is manufactured from an ionic polyimine that is stretchable, self-healable, and recyclable. By regulation of the cation–anion structure of the ionic polymine, the sensor exhibits superior preconcentration capacity and achieves accurate monitoring of iodine with a low detection limit. On the basis of the ductility and flexibility of the sensor material, an integrated wearable sensor with the functions of on-site detection and real-time alarm was prepared using a visual program. We believe that such a flexible, repairable, and malleable sensing device leads to a promising strategy of implanting it into wearable electronics, thereby realizing real-time detection and alarm of exogenous hazardous chemicals.

自修复、延展性和柔性离子聚亚胺作为便携式外源污染物检测的环境传感器
开发用于潜在化学物质检测的灵活传感平台对于探测健康参数非常重要。然而，制造已知对人类健康和环境有害的外源性化学物质的便携式柔性传感器仍然是一个挑战。在此，我们报告了一种灵活的电化学传感器，用于现场和便携式检测潜在的外源污染物碘。该传感器由可拉伸、自修复和可回收的离子聚亚胺制成。通过调节离子聚胺的阴阳离子结构，该传感器表现出优异的预浓缩能力，以低检测限实现对碘的准确监测。基于传感器材料的延展性和柔韧性，使用可视化程序制备了具有现场检测和实时报警功能的集成可穿戴传感器。我们相信，这种灵活、可修复、可延展的传感设备是将其植入可穿戴电子设备中的一种有前景的策略，从而实现外源性危险化学品的实时检测和报警。
