描述(由申请人提供)：该SBIR第一阶段计划的总体目标是演示KWJ Engineering，Inc.(KWJ)正在开发的一种新型气体传感器在臭氧监测中的应用，并在家用臭氧报警器中实施这一下一代技术。这一第一阶段计划与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。我们这项新技术的目标是瞄准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，这是一种小型屏幕印刷电化学传感器，用于开发家用臭氧警报，供患有呼吸系统疾病的个人和所有关注其暴露于臭氧的人使用。这一警报将帮助那些患有呼吸系统疾病的人通过提醒他们注意可能加剧呼吸问题或危及健康和生命的臭氧状况来管理自己的健康。在美国，超过1.18亿人生活在未达到环保局8小时臭氧标准的地区。在如此高的地面臭氧水平地区，哮喘和其他呼吸疾病的潜在发展，以及现有呼吸疾病的恶化和与这些影响相关的健康危险，都要求有一个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)承诺以商品级别的价格为广泛的应用提供高性能的气体传感。这些设备大约有一张微型SD手机卡大小，能够使用各种传统的和发育中的电解液。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广泛可调选择性、灵敏度和稳健性。这是一种新的、具有成本竞争力的高性能技术，为使用气体传感器的应用弥合了性价比差距。第一阶段计划将涉及使用各种部件制造和测试SPEC设备，以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，该传感器将被演示为家用臭氧监测器的警报致动器。 与公众健康相关：开发新的、下一代、高性能、低成本的臭氧气体传感技术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，其性能有所改善。这些传感器将构成家庭臭氧警报的核心，以帮助保护居住在地面臭氧水平较高地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.
