Abstract
A microscopic Fabry-Perot interferometer made of a thermo-sensitive polymer deposited on the facet of a single-mode fiber is proposed for highly sensitive temperature sensing. The miniature interfer-ometer was used for monitoring thermal effects in a rechargeable (lithium-ion) battery. The tempera-ture changes in the battery due to electrochemical events that occur internally during the charge/discharge stages were successfully tracked, non-invasively, with the proposed sensor. Our sensors may be used for real-time diagnostics, safety assurance, and lifetime estimation of lithium-ion batteries.
