Flexible electronics are revolutionizing device design, demanding innovative fabrication strategies. Laser processing offers unique opportunities thanks to its scalability, sustainability, and versatility. Our research group at Tomsk Polytechnic University exploits the power of laser processing to engineer nanomaterial properties for flexible devices. We have pioneered the laser-induced formation of polymer composites when irradiating nanomaterials on different substrates. This laser processing approach allows us to tune the material properties and obtain mechanically robust conductive patterns, preserve nanomaterial surface properties, and enhance gas-sensing response. We will discuss how this strategy can be applied to functionalized graphene, metallic nanoparticles, and different polymer substrates and beyond, allowing the creation of a wide range of devices, from piezoresistive and electrochemical sensors to GHz flexible antennas. The mechanism of nanomaterials and substrate modification and the potential of these structures for applications in biomedicine and sensing will be discussed.
