Abstract: We report plasma-aided printing of silver nanoparticle (AgNP) conductive lines on Polydimethylsiloxane (PDMS) surfaces- a key advancement in stretchable electronic circuits for wearable devices. This low-temperature process enables the direct printing of conductive structures on PDMS, making it compatible with current manufacturing practices for wearable electronics. Our study not only proposes a new plasma-aided method but also establishes its feasibility for printing conductive silver nanoparticle (AgNP) lines that are centimeters in length, capable of withstanding thousands of cycles of dynamic stretching and bending. Through X-ray diffraction (XRD) analysis, we established a clear relationship between the crystallinity of the printed AgNP nanostructures and plasma treatment parameters. These findings provide critical insights into optimizing plasma conditions to preserve the structural integrity and adhesion of the printed structures, thereby improving their stretchability and durability. Additionally, post-deposition inert plasma treatment was shown to enhance both the electrical conductivity and mechanical performance of the printed conductive lines. This multi-stage plasma treatment approach effectively produces durable and reliable electronic components tailored for wearable technology applications.
