Hydrogel soft actuators have been developed lots of as a novel material for smart wearable device because of their similar mechanical properties of human tissues and unique self-healing properties. Since reduced graphene oxide with carboxyl groups (CRGO) has excellent adhesiveness, conductivity, and solubility, it is regarded as proper candidate for soft actuator. Herein, we synthesized a CRGO-based hydrogel not only high stretchable, electro-responsive but also self-healing properties. The swelling properties, gel fraction and electro-mechanical response under an electric stimulus was investigated. Also, the cell viability was evaluated using cervical cancer cell line.
