Self-powered nanosensors on shim substrates

航空旅行作为一种快捷、高效的旅客和货物运输方式在全球广泛使用。毫无例外，航空旅行的最高优先级是飞机本身的结构完整性。随着全球人口的增长和移民的便利，对航空旅行的需求增加，保持安全的运行条件将成为一项重大挑战。飞机结构健康监测（SHM）是利用先进的传感器技术对飞机结构状况进行评估，通过收集、传输和分析数据来评估飞机的完整性。预防性监测和维护可以通过集成到智能机械关节中的各种传感模块来实现，这些模块可以响应物理刺激。这些轻量级的智能机械关节可以提供持续监控，并可以在灾难性问题发生之前预测到它们。我们建议在薄片衬底上开发自供电纳米传感器——创建集成压电和/或摩擦电纳米材料与传统薄片技术的智能机械关节。重要的是，这些纳米材料的结合将对垫片基板的整体重量产生微不足道的影响，但将大大扩展其功能，从单一用途（机械完整性）到多功能，智能关节（可以评估机械完整性，应变，预测损伤，并促进能量收集等）。此外，随着垫片的广泛部署，结构健康监测可以很容易地在飞机的所有关键部件上实施。这项技术将为我们的行业赞助商Shimco North America Inc.提供下一代垫片产品，并使加拿大工业在先进制造业中建立领先地位。该项目还将为HQP在纳米技术、材料科学、纳米电子学和薄膜制造等领域提供良好的培训机会，为加拿大的制造业、航空航天和绿色能源产业提供大量的创新人才

Air travel is widely used throughout the globe as a fast and efficient form of transport for both passengers and cargo. Without exception, the highest priority for air travel is the structural integrity of the aircraft itself. Maintaining safe operating conditions will become a significant challenge as the demand for air travel increases with a growing global population and ease of migration. Aircraft structural health monitoring (SHM) is the assessment of an aircraft's structural condition using advanced sensor technologies, where data can be collected, transferred and analyzed to assess vehicle integrity. Preventative monitoring and maintenance can be achieved via diverse sensing modules that are incorporated into smart mechanical joints, and which can respond physical stimuli. These lightweight, smart mechanical joints can provide constant monitoring, and can predict catastrophic problems before they occur. We propose to develop self-powered nanosensors on shim substrates - creating smart mechanical joints that integrate piezoelectric and/or triboelectric nanomaterials with traditional shim technologies. Importantly, incorporation of these nanomaterials will have a negligible impact on the overall weight of the shim substrate, but will drastically expand it's functionality from single purpose (mechanic integrity) to multi-functional, intelligent joints (that can assess mechanical integrity, strain, predict damage, and facilitate energy-harvesting, etc). In addition, with the wide deployment of shims, structural health monitoring can easily and readily be implemented throughout all critical parts of the aircrafts. This technology will provide our industry sponsor, Shimco North America Inc., a next generation shim product, and allow Canadian industry to establish a leading position in advanced manufacturing. This project will also provide excellent training opportunities for HQP in the fields of nanotechnology, material sciences, nanoelectronics and**shim manufacture, providing a large pool of innovators for Canada's manufacturing, aerospace and green energy industrie
