| Biography |
| Prof Liu is with the School of MAE since 1999. He received Bachelor degree in Materials Science and Engineering from Beijing University of Aeronautics and Astronautics, Licentiate in Technology and Doctor of Technology from the Helsinki University of Technology, Finland. From 1995 to 1999, he was a postdoctoral fellow, a senior research fellow and a visiting scholar at the Catholic University of Leuven (Belgium), Hong Kong Polytechnical University and Johns Hopkins University (USA), respectively. His research interests are smart materials and structures and their applications. He has published extensively in premier journals including Acta Materialia, Philosophical Magazine, Advanced Functional Materials, Physical Review Letters, Applied Physics Letters, Journal of Applied Physics, etc. He has been invited to give talks at various international conferences and serve as reviewer for various academic journals. |
| Research Interests |
Prof. Liu's research is focused on smart materials and structures and their applications.
Materials related research activities include but not limited to developing shape memory alloys (SMAs), fundamentals of transformation characteristics of SMAs, sensing capability of ferromagnetic shape memory materials, processing-microstructure-property relation in SMAs, fracture mechanism of FSMAs, SMA thin films and melt-spun ribbons, constrained shape recovery and influencing factors, magnetic properties of FSMAs, etc.
Application related research activities include morphing wing mechanisms of UAVs, smart-materials-based mechanisms for deployable space structures, smart-materials actuated biologically inspired micro-aerial vehicles (flapping wing system).
Other activities include SMA actuated MEMS, nitinol stent - design, fabrication, characterization, smart materials actuated underwater robot, robotic hand actuated with muscle wire. |
