Detection of air pollutants is of great importance for evaluating indoor air quality in industrial and commercial buildings, schools, hospitals, and private homes. The EPA estimates that poor indoor air quality is responsible for over 125 million lost school days and over 10 million lost work days each year and affects 33 to 50% of U.S. commercial buildings. Current approaches to air quality monitoring have multiple drawbacks. Nanostructured materials, with their small grain size, large number of grain boundaries and high specific area, present new opportunities for the development of sensors for air quality control with significantly improved properties. The proposed effort aims to develop a compact, robust, real-time monitoring system for indoor air quality, based on an array of nanostructured sensors. The array will be micromachined from self-organized nanoporous material, which will host sensitive elements with nanoengineered morphology and chemical composition, tailored to the application requirements and enabling advanced performance. During Phase I generic sensor array prototypes will be developed and their performance merit for detecting of volatile organic compounds and formaldehyde will be demonstrated. Phase Il will further develop and scale-up the technology, produce sensor arrays for specific applications, and begin commercialization. PROPOSED COMMERCIAL APPLICATIONS: Proposed technology has a significant commercial potential due to a critical demand for low-cost, real-time detectors for indoor air quality assessment. Proposed sensor array, if realized, would quickly find widespread acceptance in health care facilities, chemical, automotive, and building materials industries, schools, private homes, etc.

检测空气污染物对于评估工业和商业建筑，学校，医院和私人住宅的室内空气质量至关重要。 EPA估计，较差的室内空气质量造成超过1.25亿次损失的上学天，每年超过1000万的工作日期损失，并且影响了美国商业建筑的33％至50％。当前的空气质量监测方法具有多个缺点。纳米结构的材料，其晶粒尺寸较小，晶粒边界和较高的特定区域，为开发传感器提供空气质量控制的新机会，并具有显着改善的性能。拟议的努力旨在根据一系列纳米结构的传感器开发一个紧凑，健壮的实时监控系统，以用于室内空气质量。阵列将从自组织的纳米多孔材料中进行微加工，该材料将托管具有纳米工程形态和化学成分的敏感元素，该元素根据应用要求量身定制并实现高级性能。在I期中，将开发通用传感器阵列原型，并将证明其用于检测挥发性有机化合物的性能和甲醛。 IL阶段将进一步开发和扩展技术，为特定应用生成传感器阵列，并开始商业化。拟议的商业应用：拟议的技术具有巨大的商业潜力，这是由于对室内空气质量评估的低成本实时探测器的关键需求。拟议的传感器阵列，如果实现的话，将很快在医疗机构，化学，汽车和建筑材料行业，学校，私人住宅等中发现广泛接受。
