题目：Small-scale Energy Harvesting
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.

题目：High-efficiency Vibration Energy Harvesting for Sensor Applications
摘要：Vibration energy harvesting holds a great potential to achieve long-lifespan self-powered operations of wireless sensor networks, wearable devices and medical implants, and thus has attracted substantial interest from both academia and industry. The piezoelectric effect or electromagnetic induction has been widely adopted to convert mechanical energy to electrical energy, duo to its high energy conversion efficiency, ease of implementation and miniaturization. From the viewpoint of applications, we are most concerned about whether an energy harvester can generate sufficient power under a variable excitation. This talk systematically discusses high-efficiency vibration energy harvesting for sensor applications.
