With the widespread use of complex electrical parts composed of nanomaterials in optoelectronic and energy field, the evolution of electrical properties for these components in real operation condition should be mastered. In this work, we demonstrate a quantum-based magnetic imaging apparatus that can directly monitor the nanoscale current dynamics of complex networks noninvasively. We investigate the change of current distribution of silver nanowire networks during direct current (DC) and alternating current (AC) electrical annealing. We observe some reported phenomena at nanoscale, such as winner-takes-all dominated network under low DC voltage stress and “life” in crack during breakdown. Besides, by AC electrical annealing the stability difference of networks with high and low density are directly distinguished. Our technique is well suited for various complex network to image the dynamics of nanoscale current paths.
