This Small Business Innovation Research Phase II project will result in the development of a miniature airborne soot sensor for automotive diesel engine exhaust sensing applications. Current government regulations mandate that by 2012, all diesel vehicles sold in the United States will be equipped with onboard NOx and airborne particulate matter sensors. The proposed particulate matter sensor is based on the principle of electron spin resonance (ESR) spectroscopy. This sensor technology will be miniaturized and hardened for use in an automotive application for airborne soot sensing. Design changes intended to meet aggressive cost-reduction goals are an important feature of the project. The end result will be an automotive-grade, low-cost airborne soot sensor that can ensure end-users? compliance with new diesel engine emissions standards.The broader impact/commercial potential of this project is a reduction in airborne particulate matter emissions. Airborne particulate matter has been identified by the US government as one of six criteria pollutants with potentially serious health and environmental effects. Among the largest sources of airborne particulate matter (PM) are diesel vehicles and power plants. We propose a new, low-cost and highly specific airborne soot sensor based on a miniature electron spin resonance sensor technology. The upcoming government regulations for onboard vehicle diagnostics, combined with similar regulations abroad create a market for approximately 6.3 million airborne soot sensors per year worldwide. It is expected that the worldwide market size for onboard airborne soot sensors will grow to approximately $350M/year as a result of upcoming regulatory changes.

该小型企业创新研究第二阶段项目将开发用于汽车柴油发动机排气传感应用的微型空气烟尘传感器。目前的政府法规规定，到 2012 年，在美国销售的所有柴油车都将配备车载氮氧化物和空气颗粒物传感器。所提出的颗粒物传感器基于电子自旋共振（ESR）光谱原理。该传感器技术将被小型化和强化，以用于汽车应用中的空气烟尘传感。旨在满足雄心勃勃的成本削减目标的设计变更是该项目的一个重要特点。最终结果将是一种汽车级、低成本的空气烟尘传感器，可以确保最终用户？符合新的柴油发动机排放标准。该项目更广泛的影响/商业潜力是减少空气中颗粒物的排放。空气中的颗粒物已被美国政府确定为具有潜在严重健康和环境影响的六种标准污染物之一。空气颗粒物 (PM) 的最大来源是柴油车和发电厂。我们提出了一种基于微型电子自旋共振传感器技术的新型低成本且高度特异性的空气烟尘传感器。即将出台的车载车辆诊断政府法规与国外的类似法规相结合，在全球范围内创造了每年约 630 万个机载烟尘传感器的市场。由于即将到来的监管变化，预计机载烟尘传感器的全球市场规模将增长至约 3.5 亿美元/年。
