“…An FBG sensor was proposed by Yu et al, which was used to measure the flowrate and temperature simultaneously [9]. Wang et al established a circular target flow measurement system binding FBG [10]. Liu et al developed a flow sensor with a one-piece structural design, which using double FBG, solved the cross-sensitivity problem of temperature and strain [11].…”

A Fiber Bragg Grating (FBG) biosensor with good biocompatibility promises label-free, anti-electromagnetic interference, and non-destructive detection of stress monitoring, it holds the potential to rapidly identify the stress changes in microfluidics systems. Based on signal processing, the correlation between wavelength shift in FBG and flowrate is discussed, an alternative to manual processing of wavelength offset calculation is analyzed, and the automatic selection of FBG wavelength change under high noise conditions is realized. In addition, we propose some technologies of intelligent processing algorithms such as machine learning (BP-back propagation neural network) and moving average. Finally, the feasibility and stability of the signal processing method are verified by experimental validation and multiple data sets testing. This study provides a promising intelligent information processing strategy for rapid and accurate stress sensing of microfluidics systems.

“…In recent years, Yu et al [11], Wang et al [12], Wang et al [13], and others have applied FBG in the traditional target flowmeter and have realized the accurate and quick measurement of flow by FBG based on the circular target and a cantilever beam structure, but its structure is complex and not easy to be installed and sealed, and it fails to give full play to the advantages of FBG sensor. According to the above background, this paper proposes a set of choke target slices and sensitive elements in one of equal strength cantilever structures, on the basis of analyzing the measuring principle, and after the structure design and material processing, the feasibility of this structure is verified by experiment, and the sensor is proved sensitive and reliable.…”

Abstract:In view of problems existing in the detection of the traditional hydraulic system, such as the large volume of sensor and the low measurement accuracy, a new one-piece target type flow sensor is designed and researched based on fiber Bragg grating (FBG). A compact structure is designed, which is convenient to be dismantled, processed, and installed, based on the analysis of the principle of FBG and the structure of target type flow sensor. The force of target put in fluid flow is turned into the FBG wavelength drift, with a corresponding relationship. The problem on the cross sensitivities of the temperature and strain is solved effectively by using double FBG symmetrically pasted on the both surfaces of the cantilever. The impact on the fluid state is analyzed through simulation in the software FLUENT, and the results show that the impact was smaller than that of the traditional structure. The results of experiments in the hydraulic system show that there is a good linear relationship between the change in the dual FBG central wavelength and mass loading on the target sheet has a good linear relationship, and the sensitivity is twice that of a single FBG sensitivity.
