光纤布拉格光栅在骨骼形变监测中的应用
Application of FBG Sensors in Bone Deformation Monitoring
摘要
Abstract
In view of the problem such as large size,susceptible to electromagnetic interference and difficult to achieve long-term monitoring of the body in the traditional bone deformation monitoring technologies,fiber Bragg grating(FBG)sensing technology is used as realization principles and specific applications mode.FBG sensors with different central wavelengths were applied to the cleaned ribs for loading experiments and the deformation tendency of the bone under load was displayed in real time.In addition,using the method of pasting multi-point FBGs,the effect of changes in ambient temperature on FBG sensing measurement can be eliminated.The experimental results show that the wavelength variation of the FBG attached to the pig ribs has a linear relationship with the bending deformation caused by the force.The sensitivity of the peak shift of the fiber grating with deformation can reach 39.005 25 pm/mm.The results of this paper has certain reference value for developing micro,real-time,integrated bone health monitoring.关键词
