“…Ionic electroactive polymers (IEAPs) are advanced smart materials that have garnered signicant interest in the elds of so microrobots, articial muscles, and biomedical applications due to their unique ability to deform under electrical stimulation. [1][2][3][4][5][6][7] Specically, smart cm-scale so robots using IEAP materials possess bionic characteristics which are preferable to typical rigid actuators because of their exibility, simple construction, miniaturization, safety, biocompatibility, and low energy consumption. 1,6,[8][9][10][11] Typical IEAPs are ionic polymer metal composites (IPMCs), which are composed of a central ionexchange polymer (e.g., Naon, Flemion, and Aciplex) and electroless plated metal electrodes (e.g., Pd, Pt, Ag, and Au) on both sides.…”

“…Ionic electroactive polymers (IEAPs) are advanced intelligent materials that exhibit the unique property of deformation in response to electrical stimulation. The IEAP actuators are potential candidates for active components in microrobots due to their softness, large bending, fast response, and low operating voltages (<5 V) [6][7][8][9].…”

High-performance electroactive polymer actuators with large bending, fast response, and high durability have gained attention in the development of micromanipulators and multifunctional bionic soft robots. Herein, we developed high-performance electroactive soft actuators fabricated with ultrathin free-standing microfibrillated cellulose (MFC)-reinforced poly(3,4-ethylenedioxythiophene)/poly(4-styrenesulfonate) (PEDOT/PSS) with multi-walled carbon nanotube (MWCNT)-doped composite electrode films and ion-exchange Nafion membranes by a hot-pressing method. The prepared PEDOT/PSS-MFC-MWCNT electrodes have good film-forming properties with a Young’s modulus of 448 MPa and an electrical conductivity of 75 S/cm. The proposed PEDOT/PSS-MFC-MWCNT/Nafion soft actuators have a sustained peak displacement of 2.1 mm and a long-term cyclic stability of 94% with no degradation over 1 h at 1.0 V, 0.1 Hz. Furthermore, we fabricated soft micro-grippers based on the actuators for mimicking actual finger actions for grasping, pointing, and counting, which introduces new possibilities for the next-generation development of micromanipulators and bionic soft robotics.

“…Typical artificial muscles have been developed such as dielectric actuators, light-driven actuators, magnetic actuators, humidityresponsive actuators, and ionic actuators. [7][8][9][10][11][12][13][14] Among these artificial muscles, ionic actuators have gained wide attention on account of large displacement, low driving voltage, wide frequency band, and fast response time. [15][16][17] The ionic actuator consists of a polymer electrolyte membrane and two parallel electrode layers in a sandwich structure and its bending deformation resulted from the movement of ionic liquids within the electrolyte membrane under external voltage.…”

Highly electro‐responsive soft actuators have aroused immense attention due to their large bending deformation, fast response time, and long durability under low driving voltage. Herein we present a high‐performance ionic soft actuator using carboxylated cellulose nanofiber (CCNF), ionic liquid (IL), and polyvinyl alcohol (PVA). The proposed actuator displayed excellent actuation performances such as a large bending strain of 0.41% (peak‐to‐peak displacement of 13.6 mm), specific capacitance up to 43%, long working ability (95% maintain for 2.5 h), significantly reduced phase delay, and broad frequency bandwidth (0.1–3.0 Hz), all of which were ascribed to the strong ionic interactions of CCNF with PVA and IL. Simultaneously, bionic applications of the actuators were achieved including the active stent, bionic gripper, and bionic fingers for sliding electronic photos and human‐robot interactions. Thus, the proposed actuator provides a way for the advancement of next‐generation artificial muscles, soft robots, and human‐robot interactions.Highlights Preparing an electro‐ionic actuator using carboxylated cellulose nanofibers.
