Abstract：
Background: Artificial muscles are an active research area now. Methods: A bibliometric analysis was performed to evaluate the development of artificial muscles based on research papers and patents. A detailed overview of artificial muscles\' scientific and technological innovation was presented from aspects of productive countries/regions, institutions, journals, researchers, highly cited papers, and emerging topics. Results: 1,743 papers and 1,925 patents were identified after retrieval in Science Citation Index-Expanded (SCI-E) and Derwent Innovations Index (DII). The results show that China, the United States, and Japan are leading in the scientific and technological innovation of artificial muscles. The University of Wollongong has the most publications and Spinks is the most productive author in artificial muscle research. Smart Materials and Structures is the journal most productive in this field. Materials science, mechanical and automation, and robotics are the three fields related to artificial muscles most. Types of artificial muscles like pneumatic artificial muscles (PAMs) and dielectric elastomer actuator (DEA) are maturing. Shape memory alloy (SMA), carbon nanotubes (CNTs), graphene, and other novel materials have shown promising applications in this field. Conclusion: Along with the development of new materials and processes, researchers are paying more attention to the performance improvement and cost reduction of artificial muscles.
摘要：
背景：人工肌肉是目前一个活跃的研究领域。方法：根据研究论文和专利进行文献计量分析，以评估人工肌肉的发展。从生产国家/地区的角度详细介绍了人造肌肉的科学技术创新。机构,期刊,研究人员,被高度引用的论文，和新兴话题。结果：在科学引文索引扩展（SCI-E）和德文特创新索引（DII）中检索后，确定了1,743篇论文和1,925项专利。结果表明,中国,美国,日本在人造肌肉的科技创新方面处于领先地位。卧龙岗大学的出版物最多，Spinks是人造肌肉研究领域最有成效的作者。《智能材料与结构》是该领域最有成效的期刊。材料科学,机械和自动化，机器人是与人造肌肉最相关的三个领域。人造肌肉的类型，如气动人造肌肉（PAM）和介电弹性体致动器（DEA）正在成熟。形状记忆合金(SMA),碳纳米管(CNTs),石墨烯,石墨烯和其他新型材料在这一领域显示出了有希望的应用。结论:随着新材料和新工艺的发展,研究人员越来越关注人造肌肉的性能提高和成本降低。
