This SBIR Phase I project is directed toward the development of an inorganic electronic nose. Monitoring air quality is becoming more important as there is a growing evidence that the environment can directly affect our health. in addition, there is an increasing demand for gaseous concentration measurements in other areas as diverse as the medical industry, process control, aerospace, and the military. Applications in these fields would be best served by fast, stable, and reproducible measurements on mixed gases. Conventional gas sensors are not suitable for these applications. Array-based sensors are emerging as a new technology, which overcome the shortcomings of conventional sensors. In this project, we propose a innovative approach to prepare arrays of sensors based on semiconducting metal oxides in which the limitations associated with the current electronic noses will be eliminated. Lynntech combining microhotplate technology and combinatorial chemistry, will prepare a new generation of inorganic nose capable of fast, stable, and reproducible concentration measurements on mixed gas systems. The goal of this Phase I project is to show the feasibility of the proposed sensor devices in qualitatively and quantitatively identifying various gases. In Phase II project, Lynntech will resolve all the research and development issues and work with industrial partners to license out the proposed technology. PROPOSED COMMERCIAL APPLICATIONS: Potential applications of the proposed inorganic electronic nose are enormous. Air quality monitoring, process control, and food processing will immediately benefit from this technology. Inorganic electronic nose will also find many applications in the medical industry to identify certain skin diseases and infections and remote monitoring of patients. Lynntech's electronic nose technology can also be utilized by the military to quantitatively evaluate explosives and chemical/biological warfare agents. The proposed technology is also expected to find a use in analytical and environmental instrumentations for routine laboratory analysis.

该SBIR一期项目旨在开发一种无机电子鼻。监测空气质量变得越来越重要，因为越来越多的证据表明，环境可以直接影响我们的健康。此外，在医疗工业、过程控制、航空航天和军事等不同领域，对气体浓度测量的需求也在不断增加。对混合气体进行快速、稳定和可重复的测量将最有利于这些领域的应用。传统的气体传感器不适合这些应用。阵列传感器是一种新兴的传感器技术，它克服了传统传感器的缺点。在这个项目中，我们提出了一种创新的方法来制备基于半导体金属氧化物的传感器阵列，其中与当前电子鼻相关的限制将被消除。Lynntech将微热板技术和组合化学相结合，将制备新一代无机鼻子，能够在混合气体系统中进行快速、稳定和可重复的浓度测量。这个第一阶段项目的目标是展示所提出的传感器设备在定性和定量识别各种气体方面的可行性。在二期项目中，Lynntech将解决所有的研究和开发问题，并与工业合作伙伴合作，将拟议的技术许可出去。拟议的商业应用：拟议的无机电子鼻的潜在应用是巨大的。空气质量监测、过程控制和食品加工将立即受益于这项技术。无机电子鼻也将在医疗行业中找到许多应用，以识别某些皮肤疾病和感染以及远程监控患者。Lynntech的电子鼻技术也可以被军方用于定量评估爆炸物和化学/生物战剂。所提出的技术也有望在常规实验室分析的分析和环境仪器中找到用途。
