SBIR Phase II: High Temperature Pressure Transducers from Shape Memory Alloys

这个小型企业创新研究(SBIR)第二阶段项目将完成可集成到柴油和涡轮发动机中的成本效益高的高温压力传感设备原型的开发。一期实验结果表明，该新型金属合金作为高温压力传感器的敏感元件是可行的。然而，还需要进一步的工作来优化传感元件的制造工艺，改进换能器的设计，并为未来的生产建立制造工艺。该项目将涉及开发新型高温压力传感器的五个主要方面，并在项目结束时提出最终的封装原型。这些工作包括开发传感元件制造工艺、开发400℃传感器的制造工艺、制造传感器膜片、设计和制造衬底加热器以及封装传感元件。该公司已经收到了柴油发动机和飞机涡轮发动机行业潜在制造和商业合作伙伴的浓厚兴趣。

This Small Business Innovation Research (SBIR) Phase II project will complete the development of a prototype, cost effective high temperature pressure sensing device that can be integrated into diesel and turbine engines. Phase I results show that it is feasible to use the proposed novel metal alloy as a sensing element in a high temperature pressure transducer. However, further work needs to be performed to optimize the fabrication process of the sensing element, improve the design of the transducer, and to establish the manufacturing process for future production. The project will address five major aspects of developing a novel, high temperature pressure transducer and present a final packaged prototype at the end of the project. These are to develop the sensing element fabrication process, develop the manufacturing process for a 400 degrees C sensor, fabricate the sensor diaphragm, design and fabricate a substrate heater, and to package the sensing element. The firm has already received significant interest from potential manufacturing and commercial partners in the diesel engine and aircraft turbine engine industries.
