This research aims to develop an implantable viscoelastic gel electrode with mechanical properties similar to biological tissue that can achieve conformal contact. To this end, we intend to synthesize a hydrogel with a three-dimensional cross-linked structure through cation-pi interactions and non-covalent molecular forces between amphiphilic ionomers and conductive nanomaterials such as graphene, carbon nanotubes, and lignin. We seek to achieve a hydrogel that maintains long-term stable electrical conductivity and mechanical properties due to its high viscosity, which allows for conformal adhesion to tissue surfaces.

The implantable conductive hydrogel can be utilized as a composite electrode to deliver targeted drugs to specific tissues while monitoring physiological signals in real time. The capability for close conformal contact also makes it possible to accurately acquire neural signals distributed in difficult-to-reach areas like the human cerebral cortex, thus contributing to a meticulous understanding of brain functionality.

This research offers high developmental potential, including creating new electronic materials adaptable to the growing morphologies of biological tissues and devices for disease diagnosis and treatment. The outcomes of this research are expected to have a considerable technological impact in related academic and industrial sectors within the medical field.
