The strain measurement at the microstructure is important for the properties study and structure control. We propose two new approaches of strain characterizations at nanoscale. They are based on the use of gold nanoparticles (NPs) arrays deposited on the surface of materials.In the first approach, arrays of NPs are deposited by the electron beam lithography technique. During in situ tensile test inside a scanning electron microscope, the images of the array are progressively recorded. The treatment of these images gives access to 2D strain tensor components and NPs played the role of nanogauges. The strains at components of the microstructure and the heterogeneities of plastic deformations are evidenced. This method was coupled to the elec...
