This award provides funding for the realization of a new technology for direct printing of low-profile ceramic sensors onto curved surfaces such as turbine blades. In the proposed process a liquid phase polymer precursor ink will be electrosprayed, cured, and pyrolyzed to yield a surface-conformed ceramic sensor element. To be amenable to printing, special consideration of the ink rheology and electrical conductivity is required. The research plan is a combination of experiments and modeling of the electrospray process with consideration of sensor functionality, device resolution and durability.The research results could find broad use where surface conformance and low profile are needed for sensor applications in harsh environments such as power plants, nuclear reactors, coal mines and aircraft. The proposed printing method has the potential manufacturing advantages of being rapid and low-cost. The focus here will be on turbine blades and successful completion would enable real time, in situ thermal and mechanical measurements in turbines which operate at increasingly higher temperatures. Acquired data would enable enhanced engine control, health monitoring, and design optimization as well as contribute to improved efficiency and reliability during operation. Graduate students will be directly involved in the project and K-12 students will benefit from classroom demonstration of advanced printing process concepts.

该奖项为实现一项新技术提供资金，该技术用于将低轮廓陶瓷传感器直接印刷到曲面上，例如涡轮机叶片。在所提出的方法中，液相聚合物前体油墨将被电喷雾、固化和热解以产生表面顺应的陶瓷传感器元件。为了便于印刷，需要特别考虑油墨的流变性和导电性。该研究计划结合了电喷雾过程的实验和建模，并考虑了传感器的功能性、器件分辨率和耐用性。研究结果可以广泛用于需要表面一致性和低轮廓的传感器应用，如发电厂、核反应堆、煤矿和飞机等恶劣环境。所提出的印刷方法具有快速和低成本的潜在制造优势。这里的重点将放在涡轮机叶片上，成功完成将能够对在越来越高的温度下运行的涡轮机进行真实的实时、现场热力和机械测量。获得的数据将能够增强发动机控制、健康监测和设计优化，并有助于提高运行期间的效率和可靠性。研究生将直接参与该项目，K-12学生将受益于先进的印刷工艺概念的课堂演示。
