To further enhance performance, carbon fibers have been coated with nanomaterials including carbon nanotubes (CNTs), graphene, carbon nanospikes, among others. Traditional carbon electrodes—typically constructed from carbon fibers—are limited by their heterogeneity, which restricts their adaptability. Recent advancements have moved toward developing highly sensitive and selective carbon materials through customization. The current research is increasingly focused on developing alternative materials to replace carbon fibers, with the aim of preventing coating degradation, improving sensitivity, achieving frequency-independent properties, and lowering detection limits.
