Abstract: Aspects of the present disclosure include using particles in phase change materials to track temperature change of an object. The particles may be initially disposed at specific locations within the phase change materials. As the phase change materials transition from the solid state to the fluid state, the particles may move from the initial locations to different locations. The change in locations of the particles may be detected magnetically, electrically, optically, and/or visually. Such change may indicate that the object experienced a temperate above at least one phase transition temperature of the phase change materials.
