article description
A novel temperature-independent FBG force sensor based on a spoke-type structure is proposed. and demonstrated. The proposed sensing structure contains four symmetrical spokes and two FBGs. The FBGs with different wavelengths are bonded to the surfaces of two symmetrical spokes with an identical angle along the neutral axis direction of the spokes. Theoretical analysis and experimental results indicate that the structure is able to achieve force measurement in the range from 0 to 3 kN without suffering from the influence of the temperature within the range between -20 °C and 75 °C. This sensor can measure forces with a resolution of 0.21 kN. © 2005 IOP Publishing Ltd.
