Abstract

ABSTRACT Carbon nanotube fibers (CNTFs) have many desirable properties such as lightweight, high strength, high conductivity, and long lifetimes. Coiled CNTF is an ideal material for preparing electrochemically driven artificial muscles. While previous studies focused mainly on the actuation performance of artificial muscles made of CNTF, this study focuses on an actuator that mimics human finger movements (flexion). More specifically, the preparation of CNTF muscles were optimized by twisting with weight. Then, actuators are designed and assembled by combining all-solid-state CNTF muscles with polypropylene (PP) sheets. Moreover, a dual-electrode system, which is infiltrated by a gel electrolyte, is built into the muscle actuator. In addition, a robotic gripper is fabricated, which uses these actuators. This study can help improve the design of CNTF-based muscle-actuators and future applications in robotics. GRAPHICAL ABSTRACT

全固态碳纳米管纤维为基础的手指肌肉和机器人抓手

摘要碳纳米管纤维（CNTFs）具有许多理想的性能，如轻质、高强度、高导电性和长寿命。卷曲CNTF是制备电化学驱动人工肌肉的理想材料。虽然之前的研究主要集中在由CNTF制成的人造肌肉的致动性能上，但本研究的重点是模拟人类手指运动（屈曲）的致动器。更具体地，CNTF肌肉的制备通过随重量扭转来优化。然后，通过将所有固态CNTF肌肉与聚丙烯（PP）片相结合来设计和组装致动器。此外，在肌肉致动器中内置了一个被凝胶电解质渗透的双电极系统。此外，还制作了一个使用这些致动器的机器人夹具。这项研究有助于改进基于CNTF的肌肉致动器的设计以及未来在机器人领域的应用。图形摘要
