Prof. Liao Wei-Hsin and his PhD student, Mr. Liang Junrui, of the Department of Mechanical and Automation Engineering, The Chinese University of Hong Kong (CUHK) research on how to transform and collect piezoelectric energy from the living environment into electrical energy. They have successfully designed a circuit for improving the energy harvesting efficiency and won the Best Paper Award (Automation) for the paper entitled ‘An Improved Self-Powered Switching Interface for Piezoelectric Energy Harvesting’ at the 2009 IEEE International Conference on Information and Automation (ICIA).
