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.

描述（由申请人提供）：这个SBIR第一阶段项目的总体目标是展示KWJ工程公司（KWJ）正在开发的新型气体传感器在臭氧监测中的应用，并将这种新一代技术应用于家庭臭氧报警器。这个I期项目与NIEHS的使命直接相关，NIEHS致力于减少由环境原因引起的人类疾病和功能障碍的负担。我们对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。我们将演示这种新型气体传感器的应用，这是一种小尺寸丝网印刷电化学传感器，用于开发家庭臭氧（O3）报警器，用于患有呼吸系统疾病的个人和所有关心他们接触臭氧的人。这一警报将帮助呼吸系统疾病患者管理自己的健康，提醒他们注意可能加剧呼吸系统问题或对健康和生命构成危险的臭氧状况。美国有超过1.18亿人生活在不符合美国环保署8小时臭氧标准的地区。在如此高的地面臭氧区，哮喘和其他呼吸系统疾病的潜在发展，以及现有呼吸系统疾病的恶化，以及与这些影响有关的健康危险，都需要一种实用的家用臭氧监测仪来保护健康。KWJ的新型安培气体传感器，丝网印刷电化学传感器（SPEC），承诺以商品水平的价格为广泛的应用提供高性能气体传感。这些装置只有微型sd手机卡大小，可以使用各种传统的和正在开发的电解质。与传统的安培气体传感器相比，这提供了前所未有的大范围可调选择性、灵敏度和对环境条件的鲁棒性。这是一种新型的、具有成本竞争力的高性能技术，填补了气体传感器应用的性价比差距。第一阶段项目将包括制造和测试使用各种组件的SPEC设备，以获得高性能的臭氧检测。在相关环境条件下选择最佳的臭氧检测配置后，该传感器将被演示为家用臭氧监测仪的报警执行器。
