Abstract: Ultrasonic nano manipulation is an emerging technology, which has great potential applications in the assembly, measurement and fabrication of nano materials, handling of biological samples, manufacturing of nano sensors, new material syntheses, etc. In recent three years, the author’ research team proposed and developed a series of ultrasonic manipulating devices with the functions such as nano trapping and transfer, nano rotary driving, and nano concentration. Controlled acoustic streaming eddies are used in the nano manipulations. Compared with the nano manipulation techniques based on other physical principles, our devices have the features such as very low temperature rise at the manipulation area, little selectivity to manipulated samples, capability of implementing the manipulation on substrates given by customers. etc. In this report, we introduce the principles, structures, functions, and characteristics of the ultrasonic nano manipulating devices proposed and developed by our group, and predict the development trend of this area.

Brief Biography of the Speaker: Junhui Hu is a Chang-Jiang Distinguished Professor, China, the director of Precision Driving Lab at Nanjing University of Aeronautics and Astronautics, and the deputy director of State Key Laboratory of Mechanics and Control of Mechanical Structures, China. He received his Ph.D. Degree from Tokyo Institute of Technology, Tokyo, Japan, in 1997, and B. E. and M. E. degrees in electrical engineering from Zhejiang University, Hangzhou, China, in 1986 and 1989, respectively. He was an assistant and associate professor at Nanyang Technological University, Singapore, from 2001 to 2010. His research interest is in piezoelectric/ultrasonic actuating technology. He is the author and co-author of more than 200 papers and disclosed patents, including more than 80 full papers published in SCI journals and 1 editorial review in an international journal. He is also the sole author of monograph book “Ultrasonic Micro/Nano Manipulations” (2014, World Scientific, Singapore). Dr. Hu won the Paper Prize from the Institute of Electronics, Information and Communication Engineers (Japan) as the first author in 1998, and his research work has been highlighted by 7 international scientific media. He is a senior member of IEEE, and the editorial board member of two international journals. He was once awarded the title of valued reviewer by Sensors and Actuators A: Physical and Ultrasonics. He has given ten invited talks at international conferences, and is the honorary chairman of IWPMA 2011, held in USA.
