Abstract

The invention relates to a nano optical fiber-gold nanowire battery expansion sensor and a preparation process thereof. According to the sensor, the nanofibers and the gold nanowires are combined, and the surface plasma resonance (SPR) effect is utilized, so that the real-time high-sensitivity monitoring of the expansion state of the battery is realized. The core structure of the sensor comprises a nano optical fiber, a gold nanowire and a flexible material protection layer. When the battery expands, the SPR strength changes due to the deformation of the gold nanowires, so that the expansion degree of the battery can be accurately judged. The method has the advantages of being compact in structure, high in sensitivity, easy to integrate and the like, and is suitable for safety monitoring of various types of batteries.
