A fluid viscosity sensor using bend loss theory is presented. The sensing principle makes use of the damping characteristic of a vibrating optical fiber probe with fix-free end configuration. By measuring the frequency response of the fiber probe, the viscosity can be determined from the displacement of the fiber. Experimental results are presented for sucrose solutions of different concentrations with a viscosity varying from 1 to 15 cP.
