报告摘要：

      Small-scale energy harvesting for powering wireless sensor nodes and portable electronic devices has received intense research focus over the years. This talk presents comprehensive research work carried out in Nanyang Technological University, Singapore, on vibration and wind energy harvesting using piezoelectric materials. Various aspects of piezoelectric energy harvesting will be discussed, including its origination, linear and nonlinear harvester design topologies, analytical, finite element and equivalent circuit modelling approaches, experimental validations, harvesting circuits, various efficiency enhancement techniques, structural integrity and fatigue issues. The pros and cons of piezoelectric energy harvesting, practical applications and challenges will also be discussed.
