A Polymer optical fiber (POF) strain sensor with extremely large measurement range is described. The maximum strain of 60% was achieved by partially removing the POF cladding and core. The standard deviation of strain measurements is 0.42%. The experimental tests show that this sensor can be effectively used for the large strain measurements of viscoelastic materials.
