STTR Phase I: Packaging of Structural Health Monitoring Micro-Components

这个小型企业技术转让(STTR)第一阶段项目将为关键结构健康监测(SHM)组件开发制造、包装和接口概念。其目的是能够以低成本制造坚固耐用的致动器/传感器晶片，并将它们与恶劣的操作环境隔离，包括自然、机械或电气极端环境。目前，与SHM系统耐久性相关的问题仍然没有得到解决。在这个项目中，将开发微制造技术来制造、组装、布线和封装SHM系统组件，以实现可靠的运行。特别是，在本项目的第一阶段，用于损伤检测的压电致动器和传感器将被封装，然后在高温和潮湿条件下进行测试。通过第二阶段计划继续进行的研究将旨在包装其他支持组件，如电池和无线芯片，以及将所有这些组件集成在一起进行操作。在商业上，SHM技术在广泛的商业和国防市场上具有许多经济效益的潜力。这些系统可用于从军用或民用飞机到汽车、船舶或宇宙飞船的各种结构。第一个主要好处是，健康监测消除了定期检查的需要。第二个主要的经济效益是，持续监测系统将允许使用更有效的结构状态维修(CBM)设计方法，也就是众所周知的基于需要的维修。第三个好处是增加了结构的使用时间。

This Small Business Technology Transfer (STTR)Phase I project will develop manufacturing, packaging and interface concepts for critical Structural Health Monitoring (SHM) components. The intention is to be able to cheaply manufacture robust actuator/sensors wafers, and isolate them from harsh operating environments including natural, mechanical, or electrical extremes. Currently the issues related to SHM system durability have remained unaddressed. In this project, microfabrication techniques will be developed to fabricate, assemble, wire and package the SHM system components for robust operation. In particular, in Phase I of this project, the piezoelectric actuators and sensor used for damage detection will be packaged, and then tested in hot and wet conditions. Research continued through a Phase II program would aim to package the other supporting components such as the battery and wireless chip, as well as integrating all of these components together for operation. Commercially, SHM technologies have the potential for many economic benefits in a broad range of commercial and defense markets. These systems can be utilized by structures from military or civil aircraft, to cars, ships or spacecraft. The first major benefit is that health monitoring eliminates the need for scheduled inspections. A second major economic benefit is that a continuously monitoring system would allow for the use of the much more efficient condition based maintenance (CBM) design methodology of a structure, otherwise known as need-based repair. A third benefit would be from increased service time of the structure.
