With the aim of increasing the efficiency of maintenance and fuel usage in airplanes, structural health monitoring (SHM) of critical composite structures is increasingly expected and required. The optimized usage of this concept is subject of intensive work in the framework of the EU COST Action CA18203 "Optimising Design for Inspection" (ODIN). In this context, a thorough review of a broad range of energy harvesting (EH) technologies to be potentially used as power sources for the acoustic emission and guided wave propagation sensors of the considered SHM systems, as well as for the respective data elaboration and wireless communication modules, is provided in this work. EH devices based on the usage of kinetic energy, thermal gradients, solar radiation, airflow, and other viable energy sources, proposed so far in the literature, are thus described with a critical review of the respective specific power levels, of their potential placement on airplanes, as well as the consequently necessary power management architectures. The guidelines provided for the selection of the most appropriate EH and power management technologies create the preconditions to develop a new class of autonomous sensor nodes for the in-process, non-destructive SHM of airplane components.
为了提高飞机维护和燃料使用效率，对关键复合材料结构进行结构健康监测（SHM）的需求日益增加。在欧盟 COST 行动 CA18203“优化检测设计”（ODIN）的框架内，正在对各种能量收集（EH）技术进行深入研究，这些技术有望用作所考虑的 SHM 系统中的声发射和导波传播传感器的电源，以及各自的数据处理和无线通信模块。因此，本文对迄今为止文献中提出的基于动能、温度梯度、太阳辐射、气流和其他可行能源的 EH 设备进行了描述，并对其各自的比功率水平、在飞机上的潜在位置以及相应的必要功率管理架构进行了批判性评估。为选择最合适的 EH 和功率管理技术提供的指导方针为开发用于飞机部件在制品无损 SHM 的新型自主传感器节点创造了条件。
