This Small Business Innovation Research (SBIR) Phase I project will demonstrate the feasibility of a novel micro-fabricated gas sensor for detection of airborne volatile organic compounds (VOCs) at concentrations below 1 part-per-million. The key enabling innovation is the combination of field asymmetric ion mobility spectrometry (FAIMS) with corona discharge ionization (CDI), with both functions integrated on to a single sensor chip. This integration and the use of batch micro-fabrication techniques will deliver the high sensitivity and selectivity of ion mobility chemical detection in a small, low-cost sensor suitable for air quality monitoring and early warning fire detection. The broader impact of this will be to pave the way for prototyping and testing of a highly sensitive and selective CDI-FAIMS sensor suitable for VOC monitoring in a range of consumer and industrial applications. The adverse health effects of a range of VOCs are well-known, but effective mass-market technologies for monitoring them in domestic and work environments do not yet exist. Commercialization of a small, sensitive, low cost VOC sensor could therefore have an enormous positive impact on human health and safety.

这个小型企业创新研究（SBIR）第一阶段项目将展示一种新型微制造气体传感器的可行性，用于检测浓度低于百万分之一的空气中挥发性有机化合物（VOCs）。关键的创新是场不对称离子迁移谱（FAIMS）与电晕放电电离（CDI）的结合，这两种功能都集成在单个传感器芯片上。这种集成和批量微制造技术的使用将在适用于空气质量监测和早期预警火灾检测的小型低成本传感器中提供离子迁移率化学检测的高灵敏度和选择性。其更广泛的影响将为高灵敏度和选择性CDI-FAIMS传感器的原型设计和测试铺平道路，该传感器适用于一系列消费和工业应用中的VOC监测。一系列挥发性有机化合物对健康的不利影响是众所周知的，但在家庭和工作环境中监测它们的有效大众市场技术还不存在。因此，小型、灵敏、低成本VOC传感器的商业化可能对人类健康和安全产生巨大的积极影响。
