PURPOSE: A method and a device for measuring a strain using optical properties of a nano particle are provided to measure a strain of the nano particle by using an effect in which a color is changed when a distance between the nano particles is changed. CONSTITUTION: A method for measuring a strain using optical properties of a nano particle comprises next steps; a step(S601) for setting n strain values desired to perform a tensile test, a step(S602,S608) for setting the tensile test with a first strain value, a step(S603,S609) for transforming a polymer thin layer in which a nano particle thin film is not attached by a set strain, a step(S604,S610) for calculating photoluminescent spectrum and saving data by irradiating light energy to the transformed polymer thin film, a step(S605,S611) for deciding whether or not the tensile test is finished with the set strain value, a step(S606,S612) for setting the tensile test with a next strain value, a step(S607) for attaching generated nano particle thin film on the polymer thin film, a step(S613) for calculating a photoluminescent spectrum of only pure nano particle thin film from the calculated spectrum data and saving the data, and a step(s614) for step for calculating relation data(data for measuring the strain) between light peak frequency and the strain.
