Two strategies were used in this thesis to repair muscle tissues that require electrical stimulus: replacing the 3D polymeric scaffold with a novel conductive material—a reduced rGO aerogel modified by PTA coating and PDA coating; and coating the non-conductive polymeric scaffold with conductive coating—ppy. To fabricate an ultra-soft, ultra-thin, multifunctional, and yet subject to large scalability health monitoring system, a “masked spin coating” process was used. The as-fabricated patterned GO/rGO structure can work as not only MHMS but also a humidity responsive actuator.
