Implantable bioelectrodes are electronic devices that can monitor or stimulate biological activity by transmitting signals to and from living biological systems. Such devices can be fabricated using various materials and techniques. But, because of their intimate contact and interactions with living tissues, selection of the right material for performance and biocompatibility is crucial. In recent times, conductible hydrogels have attracted great attention as bioelectrode materials owing to their flexibility, compatibility, and excellent interaction ability.
