DESCRIPTION (provided by applicant): The risk of explosions in underground mines due to the presence of combustible gases is severe. The overall long-term objective of the proposed project is to develop and commercialize a new generation of affordable, reliable and portable hazardous gas detector in a Smart Gas Card format for use as a personal safety tool. The development of such an easy to use and wear personal monitor for the detection of combustible gases (e.g. methane) would be a substantial benefit to worker health and safety. In Phase I Synkera successfully demonstrated the feasibility of the critical element of such monitor, namely a low power, high performance reliable gas microsensor for detection of combustible gases. Now the objective of the Phase II effort is to advance the sensor technology to the maturity level required for portable detectors and to develop prototypes of Smart Combustible Gas Cardj. It will also facilitate the development of a Smart Multigas Card (methane, oxygen and carbon monoxide) required for each group of underground miners and for each miner who works alone. Portable combustible gas detectors on the market today typically catalytic bead sensors, or in the case of permanent installations, also infrared (IR) sensor technology. These are not suitable for personal monitoring due either bulk and cost (IR) or high power consumption (catalytic bead). Additionally, the stability and reliability of existing combustible gas sensors must be improved in order to enable fail-safe operation. Proposed new and improved catalytic combustible gas microsensors are based on a new microsensor platform technology, integrating precision-engineered nanostructured sensing elements with high surface area into a robust monolithic ceramic platform. In order to achieve the project objectives, in Phase II Synkera will (1) complete the sensor development and realize targeted performance; (2) develop and validate application-specific sensors, (3) identify and validate scale-up approaches, (3) develop low power electronics for portable Smart Card monitors, (4) fabricate Smart Combustible Gas Cardj prototypes and (5) develop partnerships for commercialization of microsensors and Smart Gas Card products. The proposed project is an opportunity to develop highly competitive products that address industry needs for personal safety tools, eliminate current cost and performance barriers, and provide a substantial benefit to worker health and safety, empowering individuals to make life-saving decisions in hazardous conditions as well during and in the aftermath of accidents. PUBLIC HEALTH RELEVANCE: The mining industry is one of the more challenging occupational sectors that involve adverse workers conditions, including the presence of hazardous and combustible gases. Current gas monitoring is accomplished via both fixed systems and portable instruments; however, the size and cost of current portable instruments has been a barrier to their use by all mining employees. Proposed sensor will support a new type of dramatically improved and inexpensive portable combustible gas monitors for individual use, thus enabling a new approach to alleviating intrinsic hazards of this occupation.

描述(申请人提供)：由于可燃气体的存在，在地下矿山发生爆炸的风险很大。拟议项目的总体长期目标是开发新一代负担得起、可靠和便携的智能燃气卡格式的危险气体探测器，并将其商业化，以用作个人安全工具。开发这样一种易于使用和佩戴的用于检测可燃气体(例如甲烷)的个人监测器将对工人的健康和安全有很大的好处。在第一阶段，Synkera成功地证明了这种监测仪的关键元件的可行性，即用于检测可燃气体的低功率、高性能、可靠的气体微型传感器。现在，第二阶段工作的目标是将传感器技术提升到便携式探测器所需的成熟水平，并开发智能可燃气卡的原型。它还将促进开发每一组地下矿工和每一名单独工作的矿工所需的智能多气卡(甲烷、氧气和一氧化碳)。今天市场上的便携式可燃气体探测器通常是催化珠传感器，或者在永久安装的情况下，还包括红外(IR)传感器技术。由于体积和成本(IR)或高功耗(催化珠)，这些不适合个人监控。此外，必须提高现有可燃气体传感器的稳定性和可靠性，以实现故障安全操作。提出的新型和改进的催化可燃气体微传感器基于新的微传感器平台技术，将具有高比表面积的精密工程纳米结构传感元件集成到一个坚固的单片陶瓷平台中。为了实现项目目标，Synkera在第二阶段将(1)完成传感器开发并实现目标性能；(2)开发和验证特定应用的传感器；(3)确定和验证放大方法；(3)为便携式智能卡显示器开发低功耗电子设备；(4)制造智能可燃气体Cardj原型；(5)发展微型传感器和智能燃气卡产品的商业化合作伙伴关系。拟议的项目是一个机会，可以开发具有高度竞争力的产品，满足行业对个人安全工具的需求，消除当前的成本和性能障碍，并为工人的健康和安全提供实质性好处，使个人能够在危险条件下以及在事故发生期间和之后做出拯救生命的决定。与公共健康相关：采矿业是较具挑战性的职业部门之一，涉及恶劣的工人条件，包括危险和可燃气体的存在。目前的瓦斯监测是通过固定系统和便携式仪器来完成的；然而，目前便携式仪器的尺寸和成本一直是所有采矿员工使用它们的障碍。拟议的传感器将支持一种新型的大幅改进和廉价的便携式可燃气体监测器，供个人使用，从而为减轻这一职业的内在危险提供一种新的方法。
