Thermal runaway of lithium batteries is a matter of great concern to relevant scholars. The gas pressure during the charge and discharge control process of lithium batteries is directly related to the performance of lithium batteries. Relevant scholars have been pursuing a method that can safely monitor the internal gas pressure of lithium batteries. Based on the characteristics of optical fiber sensors such as small size, anti-electromagnetic interference, and intrinsic safety, this paper designs and prepares an optical fiber gas sensor that can be used to measure the internal gas of lithium batteries. The measurement range of the sensor is 0-240kPa, and the resolution of the sensor is 0.5kPa, the sensor's accuracy reaches 5kPa, which can be used as a feasible detection method for gas generated during the working process of lithium batteries.

The calibration of length is related to the national economy and people's livelihood. The traditional calibration of length value was sent the uncalibrated instrument to the laboratory and the intrinsic error of the tested instrument was obtained in the laboratory. However, calibrating the instrument in the site produced additional error. In this article, a remote calibration method of length measurement based on optical fiber information transmission following with a proof of principle system was studied to reduce the additional error. The 1.0-level displacement guide rail was calibrated according to this method. The results showed that the relative error of guide rail displacement under different lengths was within 0.6%. The expanded uncertainties of 10 μm, 100 μm and 1 mm were analyzed respectively. The calibration results meet the actual standards of the guide rail. This optical method is a good candidate for remote calibration.

“…For example, the MZI structure can be prepared on the fiber by the reverse taper process [ 20 ] and the OMC can be prepared by fusion and drawing of two traditional communication fibers [ 21 ], where the temperature sensitivity can reach 2.326 nm/°C. In terms of depth sensing, most of them operate by amplifying the external stress on the optical fiber; for example, pressure sensitization can be performed through structures such as diaphragms of different materials, cantilevers, and cylinders [ 22 , 23 , 24 , 25 , 26 , 27 ]. The shipborne consumable temperature and depth sensor based on a beryllium bronze metal diaphragm has a sensitivity of 3.0047 nm/MPa under a pressure of 0–0.6 MPa [ 28 ].…”

The electrical sensing elements used in the traditional XBT (Expendable Bathythermograph) have problems such as low sensitivity and slow response time, and it is difficult to overcome the complex marine environment using the time–depth formula. In this paper, an ocean temperature depth sensor based on brass diaphragm and liquid filling is designed. The stress response time of FBGs with different lengths and the heat transfer time of different liquid materials are compared, and it is found that a fast response of 51 ms can be obtained by using GaInSn liquid for temperature sensing. The center deflection changes of brass diaphragms with different radii are analyzed, and the brass diaphragms with radius and thickness of 10 mm and 1 mm are selected, which still have good elastic properties under the pressure of 5 MPa. The influence of the inner metal shell section radius on the temperature and depth sensitivity is analyzed. When the final section radius is 3 mm, the temperature sensitivity of the sensor is 1.065 nm/°C, the pressure sensitivity is 1.245 nm/MPa, and the response time of temperature and depth is relatively close. Compared with the traditional temperature and depth sensors using empirical formulas for calculation, the data accuracy is improved, and a wide range of sensitivity can be tuned by adjusting the size of the internal metal shell, which can meet the needs of ocean temperature and depth data detection with high sensitivity and fast response time.
