A novel multifunctional material that integrates the electroactivity of conductive elements with the structural versatility and biocompatibility of natural polymers is electrically conductive polysaccharide-based 3D hydrogels. Polysaccharide matrices may achieve conductivity by the incorporation of conductive polymers, carbon nanotubes, and metal nanoparticles; this chapter explores the materials design and fabrication methods that facilitate this process. The methodologies influencing network design and functional performance are being, 3D bioprinting, and advanced crosslinking procedures. This chapter reviews significant structure-property correlations, including electrical, mechanical, and swelling for specific applications. The subjects addressed include the challenges of scalability, repeatability, and functional integration, along with their contemporary applications in bioelectronics, soft robotics, and tissue interfaces. This chapter aims to inform material scientists about the synthesis-structure-function paradigm driving advancements in conductive hydrogel systems.
