Description: Joint Mechanical Engineering (MNE) and Engineering and Applied Sciences (EAS) SEMINAR
DATE:
October 11, 2019
TIME:
2:00 p.m. 3:00 p.m.
LOCATION:
Textile Building, Room 101E
SPEAKER:
Mr. Sixing Xu, Ph. D. Candidate,
Tsinghua University, Beijing, China
TOPIC:
Energy Storage and Power Management for Self-Powered Systems
ABSTRACT:
The ubiquitous Internet of things (IoT) and wearable electronics have raised huge challenges on the maintenance due to the lack of power. Compared with using batteries, harvesting environmental energy to form self-powered system for each device has been more and more attractive. In this talk, I will share our work on energy harvesting, management and storage for the self-powered systems.
Specifically, I will firstly introduce an electrochemical capacitor, named micro supercapacitor (MSC), and show how we make it a promising on-chip energy storage unit in self-powered systems. After that, we will discuss the benefits and problems of using MSC as filtering component in power management circuits. I will present our solutions on reducing the capacitance decay of MSC and improving the frequency response. Moreover, our most recently work of on-chip high-frequency MSC will be shown and discussed. Finally, I will introduce triboelectric nanogenerator (TENG), which is a novel mechanical energy harvester. We will discuss our solutions and related circuits to achieve maximum energy output of TENG.
BIO:
Sixing Xu is a Ph. D. candidate in the Department of Micro Electronics at Tsinghua University, under the supervision of Prof. Xiaohong Wang. He is currently visiting in Georgia Institute of Technology, under the supervision of Prof. Zhonglin Wang. He received his Bachelor’s degree from Tsinghua University in 2015. His research interests include high-frequency micro supercapacitor, triboelectric nanogenerator, power management circuit and self-powered system. Up to now, he has published several articles in top journals in the field of energy research as the first author, such as Advanced Energy Materials (Impact factor: 24.88) and Nano Energy (Impact factor: 15.55).
