报告题目: Standardization of triboelectric nanogenerators: Progress and perspectives

报告时间:2019716日(星期二)上午9:30

报告地点:910308会议室


报告摘要:

The rapid development of the Internet of Things (IoT) and the increasing energy crisis call for a new type of energy sources. Triboelectric nanogenerators (TENGs), which can convert mechanical energies to electricity, develop quickly in recent years and catch more and more people's attention all over the world. Meanwhile the importance of the standardization for TENG has been emphasized, thus developing standardized theoretical models and experimental methods to quantitatively evaluate the performance becomes more and more important for the commercialization and industrialization of the TENG technology. This presentation will systematically review the origin of the V-Q plot (the standardized characterization tool) and the figure-of-merits (FOM, the standard for quantitatively charactering the energy output per cycle for TENG). Several essential factors which are going to be potentially involved in the standardization for TENGs will also be discussed, including the input energy, efficiency, environmental factors, and life-time assessment. At the same time, the studies about standards may open new research topics in this field. The standardization of TENG will be extremely helpful to understand and improve further applications of this emerging energy harvester. We believe that the standardization of TENG will greatly facilitate the commercialization and industrialization of TENGs in the future.


个人简介:

Prof. Yunlong Zi is an Assistant Professor in Department of Mechanical and Automation Engineering at the Chinese University of Hong Kong. Dr. Zi received his Ph.D. in Physics from Purdue University in 2014; his Bachelor of Engineering in Materials Science and Engineering from Tsinghua University in 2009. Before joining CUHK, he worked as a Postdoctoral Fellow at Georgia Institute of Technology during 2014-2017. His current research interests mainly focus on high-efficiency mechanical energy harvesting through triboelectric nanogenerators (TENG), TENG triggered high-voltage applications, and self-powered systems. As the 1st author, his research studies have been published in top-notch journals, including Nature Nanotechnology, Nature Communications, Advanced Materials, Nano Letters, ACS Nano, Nano Energy, and etc. He was honored as the winner of MRS Postdoctoral Award by Materials Research Society in 2017, as the first recipient from Georgia Tech; the Emerging Investigators by Journal of Materials Chemistry C in 2018; and one of “5 students who are transformation makers” as highlighted in Purdue homepage in 2013.
