I am currently an Associate Professor with the Guangzhou Institute of Technology, Xidian University, China. I received the Ph.D. degree from a joint program of the University of Chinese Academy of Sciences, Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Science, and Nanyang Technological University, Singapore. My research supervisors were Prof. Junrui Liang and Prof. Yaowen Yang.
With the vision of building an Internet of Moving Things free from batteries, less polluting, and sustainable, my research focuses on designing effective, reliable, and scalable battery-free IoT solutions based on kinetic energy harvesting. My research interests include energy harvesting, intermittent computing, ubiquitous computing, and battery-free IoT systems.

ViPSN: an open-source development platform specified for vibration-powered IoT devices
IEEE Internet of Things
[2019-2021]
ViPSN (an acronym for vibration-powered sensing node) is a programmable Internet of Things (IoT) platform for the development of vibration- or motion-powered sensing and transmitting systems. It serves as a reconfigurable developing platform for vibration-powered IoT applications.

ViPSN-pluck: a transient-motion-powered motion sensing system
IEEE Internet of Things
[2020-2021]
This project proposes a transient-motion-powered human motion detector, ViPSN-pluck. It is developed based on a cyber-electromechanical synergetic co-design. Instead of relying on continuous motions, such as walking and running, ViPSN-pluck explores an extreme excitation scenario by making use of a single plucking motion, which is discrete and instantaneous.
