Nanoparticles of Cu and CuNi were printed on a flexible Kapton substrates and sintered using a low-power laser. The resulting temperature sensor has linear repeatable response with the highest sensitivity in film based sensors yet reported in literature and extremely high strain tolerance to 200 cycles of bending (to three radii) and twisting. TEM work shows nanoparticles with varying degree of coalescence with connections that may act as springs to give rise to the high strain tolerance.
