This PFI: AIR Technology Translation project focuses on translating the discovery of novel microcantilever heaters to fill the need for highly sensitive and selective volatile organic compound (VOC) sensors with an ultra-low power requirement. These VOC sensors are important because of their strong impact on environmental protection and indoor air quality monitoring which has direct influence on human health and well-being. The project will result in the development of a commercially viable prototype of a novel VOC sensor packaged in the form of a miniaturized handheld device. This VOC sensor has unique features of high sensitivity and selective detection of VOCs individually and in mixtures, and operation at low heater temperature without catalyst coating. These features provide the advantages of faster and unique detection of VOCs in a complex environment, much lower power consumption, and higher reliability and operational lifetime, when compared to the leading competing pellistor and photo-ionization based sensors currently available in this market space. This project addresses the following technology gap(s) as it translates from research discovery toward commercial application. The VOC sensor to be developed will address: (i) the inability of the current technologies to perform selective detection of analytes, (ii) higher operational power requirement due to high heater temperature, and low operational lifetime due to usage of a laser or catalyst coating. A combination of unique features of the proposed VOC sensor, including low heater temperature, lack of catalyst coating, and selective VOC detection utilizing their physical properties, enables it to address the aforementioned limitations of the current technology. In addition, the personnel involved in this project, at both graduate and undergraduate levels, will receive entrepreneurship and technology translation experiences through participation in the project activities directly related to commercialization and mentorship from the industrial partner. The project engages Tangidyne Inc. to guide the commercialization aspects of the sensor developed, and provide unique business mentorship to the graduate and undergraduate students involved in this technology translation effort from research discovery toward commercial reality.

该PFI：空气技术翻译项目的重点是翻译新型微型管理器加热器的发现，以满足具有超低功率要求的高度敏感和选择性挥发性有机化合物（VOC）传感器的需求。 这些VOC传感器非常重要，因为它们对环境保护和室内空气质量监测的强烈影响，对人类健康和福祉有直接影响。 该项目将导致以微型手持设备形式包装的新型VOC传感器的商业可行原型的开发。该VOC传感器具有高灵敏度的独特特征，并且可以单独和混合物中的VOC选择性检测，并且在没有催化剂涂层的情况下在低加热器温度下运行。 与当前在该市场空间中目前可用的领先的竞争磁场和基于光电离的传感器相比，这些功能在复杂的环境中提供了更快，更独特的VOC检测，更低的功耗以及更高的可靠性和运营寿命。 该项目解决了以下技术差距，因为它从研究发现转化为商业应用。要开发的VOC传感器将解决：（i）当前技术无法对分析物进行选择性检测，（ii）由于加热器温度较高而导致的较高的操作功率需求以及由于激光或催化剂涂料的使用而导致的操作寿命较低。拟议的VOC传感器独特功能的组合，包括使用其物理特​​性的缺乏催化剂涂料以及选择性VOC检测，使其能够解决当前技术的上述限制。此外，在研究生和本科级别上，参与该项目的人员将通过与工业合作伙伴的商业化和指导直接相关的项目活动来获得企业家和技术翻译经验。该项目与Tangidyne Inc.一起指导开发传感器的商业化方面，并为参与从研究发现到商业现实的这项技术翻译工作的研究生和本科生提供独特的商业指导。
