I am now a Ph.D. at University of Chinese Academy of Sciences, jointly trained with Nanyang Technological University, Singapore and ShanghaiTech University, China. I am also with the Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences. My research supervisors are Prof. Junrui Liang | 梁俊睿教授 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 system.

Mechanical potential energy pre-charging

IEEE/ASME Transactions of Mechatronics


Different from the solar or RF energy harvesting solutions, which might be constrained by fluctuating sources, the kinetic energy harvester using potential energy pre-charging mechanism has a unique feature to provide a highly reliable energy supply to self-powered applications.


ViPSN: an open-source development platform specified for vibration-powered IoT devices

IEEE Internet of Things


ViPSN (acronym of 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


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.
