Abstract
In this study, we demonstrate the fabrication of Laser-Induced Graphitic Carbon (LIGC) electrodes on flexible Kevlar cloth for showing their potential use as wearable electrochemical sensors. Kevlar was converted into LIGC using an inexpensive hobbyist 450 nm laser, highlighting a cost-effective method for creating graphitic carbon on cloth. Laser parameters were optimized to achieve low sheet resistance. Morphological and spectroscopic characterization revealed that LIGC had an intricated 3D porous morphology and confirmed the formation of sp2 hybridized carbon. Electrochemical analysis in [Fe(CN)6]4−, Fe2+/3+ showed a quasi-reversible electron transport mechanism on the surface of graphitic carbon, primarily controlled by mass diffusion processes.
