This work describes a wireless wearable ring-based multiplexed chemical sensor platform for rapid electrochemical monitoring of explosive and nerve-agent threats in vapor and liquid phases. The ring-based sensor system consists of two parts: a set of printed electrochemical sensors and a miniaturized electronic interface, based on a battery-powered stamp-size potentiostat, for signal processing and wireless transmission of data. A wide range of electrochemical capabilities have thus been fully integrated into a 3D printed compact ring structure, toward performing fast square-wave voltammetry and chronoamperometric analyses, along with interchangeable screen-printed sensing electrodes for the rapid detection of different chemical threats. High analytical performance is demonstrated despite the remarkable miniaturization and integration of the ring system. The attractive capabilities of the wearable sensor ring system have been demonstrated for sensitive and rapid voltammetric and amperometric monitoring of nitroaromatic and peroxide explosives, respectively, along with amperometric biosensing of organophosphate (OP) nerve agents. Such ability of the miniaturized wearable sensor ring platform to simultaneously detect multiple chemical threats in both liquid and vapor phases and alert the wearer of such hazards offers considerable promise for meeting the demands of diverse defense and security scenarios.

基于可穿戴式环的传感平台,可检测化学威胁

这项工作描述了一种无线可穿戴式基于环的多路复用化学传感器平台,用于快速电化学监测气相和气相中的爆炸物和神经毒剂威胁。基于环的传感器系统由两部分组成:一套印刷的电化学传感器和一个基于电池供电的邮票大小的恒电位仪的微型电子接口,用于信号处理和数据的无线传输。因此,广泛的电化学功能已完全集成到3D打印的紧凑型环形结构中,以进行快速方波伏安法和计时电流分析,以及可互换的丝网印刷传感电极,用于快速检测不同的化学威胁。尽管环系统显着地小型化和集成化,但仍显示出较高的分析性能。穿戴式传感器环系统的强大功能已被证明分别用于硝基芳香族和过氧化物炸药的灵敏,快速伏安和安培监测,以及有机磷酸酯(OP)神经毒剂的安培生物传感。微型可穿戴传感器环平台能够同时检测液相和气相中的多种化学威胁并向佩戴者发出警报的这种能力为满足各种防御和安全场景的需求提供了可观的希望。穿戴式传感器环系统的强大功能已被证明分别用于硝基芳香族和过氧化物炸药的灵敏,快速伏安和安培监测,以及有机磷酸酯(OP)神经毒剂的安培生物传感。微型可穿戴传感器环平台能够同时检测液相和气相中的多种化学威胁并向佩戴者发出警报的这种能力为满足各种防御和安全场景的需求提供了可观的希望。穿戴式传感器环系统的强大功能已被证明分别用于硝基芳香族和过氧化物炸药的灵敏,快速伏安和安培监测,以及有机磷酸酯(OP)神经毒剂的安培生物传感。微型可穿戴传感器环平台能够同时检测液相和气相中的多种化学威胁并向佩戴者发出警报的这种能力为满足各种防御和安全场景的需求提供了可观的希望。
