机械发光（ML）-钙钛矿传感器已显示出在复合材料结构中实时碰撞传感的潜力。传感器可以嵌入到结构中，用于现场和实时结构健康监测（SHM）应用。我们以前的工作证明了用于SHM系统的柔性ML-钙钛矿传感器的潜力以及传感器嵌入纤维增强复合材料结构中的可能性。然而，传感器预测撞击定位的可行性仍然未被探索。本文研究了复合材料层合板冲击定位传感器的潜力。在本文中，嵌入式ML-钙钛矿传感器被放置在整个复合板中以监测主体结构。通过监测和关联传感器电流的变化，可以预测结构中的碰撞位置。实验结果表明，ML-钙钛矿传感器可以准确地检测和定位时，嵌入在复合材料结构的冲击事件。这项工作揭示了ML-钙钛矿传感器在复合材料损伤检测和定位预测方面的潜力。
Mechanoluminescence (ML)-perovskite sensors have shown potential for real-time impact sensing in composites structure. The sensors can be embedded in the structure for in-situ and real-time structural health monitoring (SHM) applications. Our previous work demonstrated the potential of a flexible ML-perovskite sensor for SHM systems and the possibility of sensor embedment in a fiber-reinforced composite structure. However, the viability of the sensor to predict impact localization remains unexplored. This paper investigates the potential of the sensors for impact localization in composite laminates. Herein, embedded ML-perovskite sensors are placed throughout a composite plate to monitor the host structure. By monitoring and correlating the changes in the electrical current of the sensors, it is possible to predict the impact location in the structure. The experimental results show that the ML-perovskite sensor can accurately detect and locate impact events when embedded in a composite structure. This work reveals the potential of ML-perovskite sensors for damage detection and localization prediction in composite materials.
