Self-powered nanosensors on shim substrates

航空旅行作为一种快速、高效的旅客和货物运输方式，在全球范围内被广泛使用。无一例外，航空旅行的最高优先事项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，航空旅行的需求增加，维持安全的运营条件将成为一项重大挑战。飞机结构健康监测(SHM)是使用先进的传感器技术对飞机的结构状况进行评估，其中可以收集、传输和分析数据以评估车辆的完整性。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。这些轻便、智能的机械关节可以提供持续的监控，并可以在灾难性问题发生之前对其进行预测。我们建议在垫片衬底上开发自供电纳米传感器--创造将压电和/或摩擦电纳米材料与传统垫片技术相结合的智能机械关节。重要的是，这些纳米材料的加入对垫片基板的整体重量的影响微乎其微，但将极大地扩展其功能，从单一用途(机械完整性)扩展到多功能、智能关节(可以评估机械完整性、应变、预测损伤和促进能量收集等)。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中实施。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领域确立领先地位。该项目还将在纳米技术、材料科学、纳米电子学和垫片制造领域为HQP提供极好的培训机会，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者

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 andshim manufacture, providing a large pool of innovators for Canada's manufacturing, aerospace and green energy industrie
