传感技术的最新发展引发了大量的研究兴趣，探索新的自供电，廉价，紧凑和灵活的压力传感器与结构健康监测（SHM）的应用潜力。在此，我们评估了嵌入式机械发光（ML）和钙钛矿压力传感器的性能，该传感器集成了机械发光和钙钛矿材料的物理原理。对于一个连续的原位SHM，它是至关重要的，以评估嵌入到复合材料结构的传感设备的能力。对传感器在玻璃纤维增强复合材料中的嵌入过程进行了实验研究。将一系列具有和不具有ML的器件嵌入复合材料层压板内，并在不同条件下收集信号响应。我们还展示了一个成功的封装过程，以使该设备能够承受复合材料的制造条件。结果表明，该传感器在不同的载荷条件下具有不同的信号，可用于先进复合材料结构的现场SHM。
Recent developments in sensing technologies have triggered a lot of research interest in exploring novel self-powered, inexpensive, compact and flexible pressure sensors with the potential for structural health monitoring (SHM) applications. Herein, we assessed the performance of an embedded mechanoluminescent (ML) and perovskite pressure sensor that integrates the physical principles of mechanoluminescence and perovskite materials. For a continuous in-situ SHM, it is crucial to evaluate the capabilities of the sensing device when embedded into a composite structure. An experimental study of how the sensor is affected by the embedment process into a glass fiber-reinforced composite has been conducted. A series of devices with and without ML were embedded within a composite laminate, and the signal responses were collected under different conditions. We also demonstrated a successful encapsulation process in order for the device to withstand the composite manufacturing conditions. The results show that the sensor exhibits distinct signals when subjected to different load conditions and can be used for the in-situ SHM of advanced composite structures.
