Low SWaP Phosgene Clip Detector

项目摘要 光气是必不可少的日常生活中使用的产品，如软泡沫，热塑性塑料， 聚氨酯、密封剂和弹性体。它也是许多塑料、杀虫剂和 大药厂但是，在室温下光气是一种毒性极强的无色气体， 引起眼睛和皮肤刺激的即时症状，以及呼吸窘迫的症状，如咳嗽， 胸闷、呼吸困难、肺炎或心力衰竭，可能在术后6-24小时才出现 exposure.因此，生产光气的设施需要大型光气检测器进行广域监测， 以及用于监测个人的光气指示器徽章。电化学检测器执行实时 使用音频警报监测光气暴露，但它们价格昂贵，只能安装在有限的 地点佩戴式比色指示器徽章是监测个人的标准手段。它表明 光气的存在，但缺点是，工人必须不断地看， 徽章，以确保他们的人身安全，因为它不会主动提醒他们的危险。智能光学系统， Inc. (IOS)建议开发一种低SWaP（尺寸，重量和功率），低成本的可穿戴光气传感器， 将结合具有高灵敏度的高选择性比色光气传感器膜的个体 当工人暴露在超过1000克的光气中时， 设定阈值。

Project Summary Phosgene is essential to the manufacturing of products used in everyday life such as flexible foams, thermoplastic polyurethane, and sealants and elastomers. It is also a building block for many plastics, pesticides, and pharmaceuticals. However, at room temperature phosgene is an extremely toxic, colorless gas—exposure can cause immediate symptoms of eye and skin irritation, and symptoms of respiratory distress such as coughing, tightness in the chest, difficulty breathing, pneumonia, or heart failure that may not manifest until 6-24 hours after exposure. Therefore, phosgene-producing facilities need large phosgene detectors for wide-area monitoring, as well as phosgene indicator badges for monitoring individuals. Electrochemical detectors perform real-time monitoring with audio alarms for phosgene exposure, but they are expensive and can only be installed in limited locations. A wearable colorimetric indicator badge is the standard means of monitoring individuals. It indicates the presence of phosgene by changing color, but the disadvantage is that the worker must constantly look at the badge to ensure their personal safety because it does not actively alert them to danger. Intelligent Optical Systems, Inc. (IOS) proposes to develop a low SWaP (size, weight, and power), low-cost wearable phosgene sensor for individuals that will incorporate a highly selective colorimetric phosgene sensor film with a highly sensitive optical readout unit that will trigger an audible alarm when the worker is exposed to phosgene levels that exceed a set threshold.
