With the advance of soft electronic industry, soft electro-ionic artificial muscles based on electro-active polymer have been actively investigated from the practical viewpoint. However, due to the few drawbacks of the soft electro-ionic artificial muscles, they have not yet been applied to the practical applications until know. Herein, we report soft electro-ionic artificial muscles based on three dimensional graphene-carbon nanotube-nickel nanostructures (G-CNT-Ni). The G-CNT-Ni were blended in both polymeric electrodes and ionic membranes to fabricate a strong and large-bending soft electro-ionic artificial muscle. Importantly, the G-CNT-Ni exhibited remarkable electrochemical reactivity due to the synergistic effects of large specific surface area, three-dimensionally networked structures, and no restacking phenomena. Moreover, reinforcement of the G-CNT-Ni makes significantly improved blocking force and bending actuation of soft electro-ionic artificial muscle. This investigation can opens up a new way to apply soft electro-ionic artificial muscles to practical applications in next-generation electronic devices.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
