This paper presents the development of "moon bricks" fabricated using in situ lunar regolith and a minimal binder, integrated with Fiber Bragg Grating (FBG) sensors. These sensors transform the bricks into smart components capable of monitoring temperature or stress induced deformation during both manufacturing phase and operational lifespan. The incorporation of FBG sensors facilitates real-time, on-condition maintenance, thereby enhancing the safety and reliability of lunar outposts and associated infrastructures.This study focuses on the experimental validation of temperature monitoring within smart bricks under low-temperature conditions in a climatic chamber. The results demonstrate good agreement for static measurements, providing a preliminary validation for the instrumentation. This research marks a significant step towards realizing sensorized building blocks with local resources, thus paving the way for advanced, intelligent lunar construction, ensuring long-term structural integrity and operational safety.
