“…Soft actuators that can produce mechanical work when stimulated by heat, humidity, light, or electric field have drawn tremendous attention in the fields of bioinspired robotics, biomedical devices, and haptic devices. [ 1–5 ] Among several types of soft actuators including dielectric elastomers and piezoelectric polymers, ionic electroactive polymer (iEAP) actuators, consisting of an ion‐conductive membrane sandwiched between two electrodes, are particularly attractive owing to their lightweight, simple fabrication, precise electrical control of actuation, large and fast deformation under a low operation voltage less than 2 V. [ 6–8 ] Various electrodes and ion‐conductive polymers have been investigated to improve the bending performance of iEAP actuators. [ 9–19 ] For example, 3D nanoarchitectured materials with high surface‐area such as carbon nanotube/graphitic carbon nitride hybrids, [ 20 ] laser‐scribed reduced graphene oxides, [ 21 ] and conductive metal‐organic frameworks, have been developed as flexible, highly conductive, and crack‐free electrodes.…”
