Strong, Powerful Artificial Muscles Yarns and Fibers Who’s Multifunctionality Provides Intelligence and the Ability to Harvest Energy

Ray H. Baughman

Successive generations of artificial muscle yarns and fibers have provided the understanding needed to progressively increase muscle performance. While our original electrochemical muscles based on carbon nanotube (CNT) sheets provided only about 0.1% tensile strokes, our present coiled yarn electrochemical CNT muscles provide tensile stokes as high as 12%, and 65 times the work capacity per cycle and 100 times the load-lifting capability as the same size natural muscle. Our polymer muscles made from fishing line or sewing thread, which are thermally, electrothermally, or chemically powered, can rotate at 100,000 rpm, contract 49%, generate 5 times the gravimetric power of a car engine, lift 100 times heavier loads than the same length and weight human muscle, or actuate at 7.5 cycles/s for millions of cycles. The strokes of these polymer muscles has been increased to a remarkable 9000% for applications as diverse as thermal energy harvesting and comfort-adjusting clothing. We have very recently shown that our CNT muscles can be operated in reverse to generate a gravimetric electrical power output that is higher than for any reported mechanical energy harvester for few Hz to 600 Hz frequencies. These “twistron” harvesters were used in the ocean to harvest wave energy, combined with thermally-driven artificial muscles to convert temperature fluctuations to electrical energy, sewn into textiles for use as self-powered respiration sensors, and used to power a LED and to charge a storage capacitor.

He was named the Honorable Yang Shi-Xiang Professor of Nankai University and the Honorable Tang Aoqing Professor of Jilin University in 2010 and was listed 30th in the Top 100 Material Scientists of the Decade (2000-2010). The Baughman laboratory was established in his honor in China in 2014 at the Jiangnan Graphene Research Institute in Changzhou.

Advanced Fibre Composites – Issues and Challenges

Professor Lin Ye

Fibre-reinforced polymer composites are widely used in today’s aerospace, green energy, marine, and transportation industries, because of their high specific strength and specific stiffness in comparison with those of conventional materials. Over years, significant advances have been made to substantially enhance performance of composites by enhancing the properties of fibres and matrices and by optimising interfaces between them. In recent years, nano-scale reinforcements have been used to further enhance properties of composites, and the multi-functionality (e.g. self-sensing and self-healing) has attracted attention of many researchers in the areas. This talk highlights the development of advanced composites in the past half-century addressing the processing-structure-property relationship of composites. It also articulates some recent development of composite materials and structures with multi-functionality for self-sensing and self-healing addressing some key issues and challenges that face researchers.

Biography: Lin Ye currently is a full professor at the School of Aerospace, Mechanical and Mechatronic Engineering and the Director of the Centre for Advanced Materials Technology of The University of Sydney. He received his BEng degree from Harbin Engineering University in 1982, and MEng in 1984 and PhD in 1987 from Beijing University of Aeronautics and Astronautics. He then joined the Xi’an Jiaotong University as a Lecturer in early 1988. He joined The University of Sydney in July 1992 after working as an Alexander von Humboldt Fellow at the Institute for Composite Materials (IVW GmbH) 1990-1992. His major research interests are in the areas of composites science and technology, smart materials and structures, nano-materials and nano-composites, structural integrity and durability. He was elected a Fellow of the Australian Academy of Engineering and Technology (ATSE) in 2005.
