Strain sensing based on radiative emission-absorption mechanism using dye-doped polymer optical fiber [PDF]

, 2017
A stress sensor based on a dye-doped polymeric optical fiber is able to detect stress by simple comparison of two luminescence peaks from a pair of energy transfer organic dyes. Coumarin 540A (donor) and Rhodamine 6G (acceptor) were doped in the core and
