Abstract

High-performance artificial muscles featuring large bending strain, rapid response, low-power operation, excellent electromechanical durability, and biocompatibility are critically important for advancing cm-scale soft robotics, next-generation flexible rehabilitation devices, and microfluidic technologies. Herein, we proposed a high-performance sandwich-structured ionic electroresponsive artificial muscle based on self-supporting carboxylated cellulose nanofibers (CCNF) reinforced with poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PP) and graphene oxide (GO) composite electrode membranes. The developed CCNF–PP–GO artificial muscle shows a substantial bending strain of 0.14 %, a large peak displacement reaching ±8.3 mm at an ultra-low voltage (1.0 V, 0.1 Hz), and a long-term actuation stability (<2 % degradation) over 1000 cycles, attributed to the well-formed electrode membranes with high conductivity and stretchability, strong interfacial adhesion, high water retention capacity, and fast ion conductivity. Importantly, the proposed artificial muscles demonstrated real-world applicability in flexible grippers, bionic starfish, and microfluidic sorting devices, offering new possibilities for the development of soft robotics and microfluidic technologies.

高性能电活性人造肌肉，具有自支撑羧化纤维素纳米纤维增强PEDOT:PSS/氧化石墨烯电极膜

高性能人造肌肉具有大弯曲应变、快速响应、低功耗操作、优异的机电耐久性和生物相容性，对于推进厘米级软机器人、下一代柔性康复设备和微流体技术至关重要。在此，我们提出了一种高性能的三明治结构离子电反应人工肌肉，基于自支撑羧化纤维素纳米纤维（CCNF），聚（3,4-乙烯二氧噻吩）、聚（苯乙烯磺酸盐）（PP）和氧化石墨烯（GO）复合电极膜增强。开发的CCNF-PP-GO人造肌肉在超低电压（1.0 V, 0.1 Hz）下显示出0.14 %的可观弯曲应变，±8.3 mm的峰值位移，以及超过1000次循环的长期驱动稳定性（<；2 %降解），这要归因于结构良好的电极膜具有高导电性和拉伸性，强界面附着力，高保水能力和快速离子导电性。重要的是，所提出的人造肌肉在柔性抓取器、仿生海星和微流控分选装置中展示了现实世界的适用性，为软机器人和微流控技术的发展提供了新的可能性。

期刊介绍： Sensors and Actuators A: Physical brings together multidisciplinary interests in one journal entirely devoted to disseminating information on all aspects of research and development of solid-state devices for transducing physical signals. Sensors and Actuators A: Physical regularly publishes original papers, letters to the Editors and from time to time invited review articles within the following device areas: • Fundamentals and Physics, such as: classification of effects, physical effects, measurement theory, modelling of sensors, measurement standards, measurement errors, units and constants, time and frequency measurement. Modeling papers should bring new modeling techniques to the field and be supported by experimental results. • Materials and their Processing, such as: piezoelectric materials, polymers, metal oxides, III-V and II-VI semiconductors, thick and thin films, optical glass fibres, amorphous, polycrystalline and monocrystalline silicon. • Optoelectronic sensors, such as: photovoltaic diodes, photoconductors, photodiodes, phototransistors, positron-sensitive photodetectors, optoisolators, photodiode arrays, charge-coupled devices, light-emitting diodes, injection lasers and liquid-crystal displays. • Mechanical sensors, such as: metallic, thin-film and semiconductor strain gauges, diffused silicon pressure sensors, silicon accelerometers, solid-state displacement transducers, piezo junction devices, piezoelectric field-effect transducers (PiFETs), tunnel-diode strain sensors, surface acoustic wave devices, silicon micromechanical switches, solid-state flow meters and electronic flow controllers.
