Abstract Flexible electrodes are essential components of flexible electronic devices. However, fabricating these is challenging because conventional methods not easily applicable to them. substrates, such as polymer, fabric, and paper, delicate require specialized deposition techniques. To address this challenge, we present a novel, single-step method using DC sputtering shadow mask fabricate high-resolution silver on polymer fabric substrates. This approach cost-effective, overcomes the limitations multi-step processes, enables direct electrode patterning. In our study, produced used thermoplastic polyurethane (TPU) with thickness 310 micrometers substrate, which has an elongation at break 749.39%.
