Abstract:
The increasing demand for portable and intelligent sensing systems has stimulated research on graphene-based materials for next-generation gas sensors. Among the different fabrication methods, Laser-Induced Graphene (LIG) produced by the LightScribe technique offers a rapid, low-cost, and flexible approach for the development of conductive sensing structures [1,2]. This work focuses on the optimization of processing parameters involved in the LightScribe fabrication process of graphene transducers [3]. Different engraving modes, laser cycles, and preparation conditions were investigated to evaluate their influence on the graphitization process and the electrical and structural properties of the fabricated devices. The produced samples were characterized using structural, morphological, and electrical analysis techniques. The results demonstrate that processing parameters significantly affect the morphology, conductivity, and reduction degree of the graphene layers. Optimal fabrication conditions enabled the development of stable and reproducible flexible graphene transducers suitable for future gas sensing and electronic nose applications [2,4].
