Home Ozone Monitor Incorporating Low Cost High Performance Printed Gas Sensors

描述（由申请人提供）：SBIR第一阶段计划的总体目标是演示KWJ工程公司正在开发的新型气体传感器的应用。(KWJ)臭氧监测，并在家庭臭氧报警器中实施这种下一代技术。该第一阶段计划与NIEHS的使命直接相关，该使命旨在减轻环境原因引起的人类疾病和功能障碍的负担。这项新技术的目标是针对家庭和工作场所中对个人健康和安全至关重要的关键应用。我们将展示这种新的气体传感器，一个小格式的丝网印刷电化学传感器，为呼吸系统疾病的个人和所有那些关心他们暴露于臭氧的家庭臭氧（O3）报警的发展应用。这种警报将帮助那些有呼吸系统疾病的人管理他们的健康，提醒他们臭氧状况可能会加剧呼吸系统问题或危及健康和生命。在美国，超过1.18亿人生活在未达到EPA 8小时臭氧标准的地区。在如此高的地面臭氧区域，哮喘和其他呼吸道疾病的发展潜力，以及现有呼吸道疾病的恶化以及与这些影响相关的健康危险，需要一种实用的家用臭氧监测仪来保护健康。KWJ的新型电流型气体传感器，丝网印刷电化学传感器（SPEC），承诺以商品级价格为广泛的应用提供高性能的气体传感。这些设备的大小与micro-SD手机卡差不多，能够使用各种传统和开发的电解质。与传统的电流型气体传感器相比，这提供了前所未有的对环境条件的宽范围可调选择性、灵敏度和鲁棒性的访问。这是一种具有成本竞争力的高性能新技术，可弥合使用气体传感器的应用的成本性能差距。第一阶段计划将涉及制造和测试的SPEC设备使用各种组件，旨在获得高性能的臭氧检测。在选择了在相关环境条件下检测臭氧的最佳配置后，该传感器将被证明是家用臭氧监测器的报警执行器。 公共卫生相关性：新的、下一代、高性能、低成本的臭氧气体传感技术的开发将使气体传感更广泛地用于健康和安全保护。拟议的计划将提供一种新的，功能强大的丝网印刷气体传感器格式，与目前可用的臭氧传感器相比，性能有所改善。这些传感器将构成家庭臭氧警报器的核心，以帮助保护生活在高地面臭氧区的呼吸系统疾病患者的健康。

DESCRIPTION (provided by applicant): The overall goal of this SBIR Phase I program is to demonstrate application of a new class of gas sensor under development by KWJ Engineering, Inc. (KWJ) to ozone monitoring and to implement this next generation technology in a home ozone alarm. This Phase I program is directly related to the mission of NIEHS, which addresses reduction of the burden of human disease and dysfunction arising from environmental causes. Our aim for this new technology is to target key applications critical to personal health and safety, in the home and in the workplace. We will demonstrate the application of this new gas sensor, a small format screen printed electrochemical sensor, for development of a home ozone (O3) alarm for individuals with respiratory diseases and all those concerned about their exposure to ozone. This alarm will help those with respiratory conditions to manage their health by alerting them to ozone conditions that may exacerbate respiratory problems or be dangerous to health and life. Over 118 million people in the United States live in areas of nonattainment of the EPA 8 hour ozone standard. The potential for development of asthma and other respiratory conditions, as well as the aggravation of existing respiratory conditions and the health dangers associated with these effects in such high ground level ozone areas calls for a practical home ozone monitor for health protection. KWJ's new class of amperometric gas sensor, the screen-printed electrochemical sensor (SPEC), promises to deliver high performance gas sensing for a wide range of applications at commodity-level prices. These devices, which are about the size of a micro-SD cell phone card, are able to use a variety of conventional and developmental electrolytes. This provides unprecedented access to a wide range of tunable selectivity, sensitivity and robustness to environmental conditions compared to conventional amperometric gas sensors. This is a new, cost-competitive and high performance technology that bridges the cost-performance gap for applications using gas sensors. The Phase I program will involve fabrication and testing of SPEC devices using a variety of components directed at obtaining high performance for ozone detection. After selection of the best configuration for detecting ozone under relevant environmental conditions, the sensor will be demonstrated as an alarm actuator for the home ozone monitor. PUBLIC HEALTH RELEVANCE: Development of new, next generation, high performance, low cost gas sensing technologies for ozone will make gas sensing more widely available for health and safety protection. The proposed program will provide a new, powerful screen printed gas sensor format with improved performance compared to currently available ozone sensors. These sensors will form the heart of a home ozone alarm to help protect the health of people with respiratory conditions living in high ground level ozone areas.
