摘要： The invention relates to a fibre sensor that enables the propagation of infrared light at at least one wavelength of 0.8 to 25 micrometres, the fibre successively comprising along its length a first infrared waveguide section (23), a second detection section (25) intended to come into contact with an external environment in order to detect infrared signatures interfering with the propagation of the evanescent waves propagating along the fibre (2), and a third infrared waveguide section (27). The invention is characterized in that, in the second fibre section (25) that has the detection role, the fibre (2) is constituted of a curved part, the radius of curvature of which is locally less than 2.3 millimetres.

摘要： Method for operando characterization of the chemical composition of a battery cell (12), comprising the following steps :
- inserting an optical fiber (14) made of chalcogenide glass through the battery cell (12),
- cycling the battery (12),
- while cycling the battery (12), generating an optical signal and transmitting it through the optical fiber (14),
- detecting, using an infrared spectrometer (20), the transmitted optical signal at an output extremity (140) of the optical fiber (14),
- recording the detected optical signal over time,
- locating signature wavelengths for which the optical signal intensity is above a predetermined threshold within the spectrum,
- associating said located signature wavelengths to at least one predetermined chemical species.
