The visualized dual-modal stress-temperature sensing refers to the ability of a sensor to provide real-time and visible information about both stress and temperature and has indeed attracted significant interest in various fields. However, the development of convenient methods for achieving this capability remains a challenge. In this work, a dual-modal stress-temperature sensor is successfully fabricated using a ZnS/Cu@CsPbBrI glass ceramics (GCs)/polydimethylsiloxane (PDMS) (ZCP) composite film. The tunable ML color is achieved by modulating the concentration of CsPbBrI GCs in the ZCP composite films based on the light conversion process from ZnS/Cu to CsPbBrI GCs. Additionally, the stress and temperature can be visualized simultaneously by integrating the ML intensity and ML color of the ZCP composite film. This feature allows for the real-time monitoring of automotive tire temperature by embedding the ZCP composite film on the tire surface, enabling a strong and stable response to both stress and temperature changes. Overall, this work offers a convenient, efficient, and repeatable approach for achieving visualized dual-modal stress-temperature sensing in the fields of mechanical engineering, structural health monitoring, and intelligent devices.
