Concept Designs for Vibration Energy Harvesting Employing Nonlinear Dynamics

The era of Industrial Internet of Things requires the development of broadband energy harvesters with the capability to energize low-power electronics for self-powered sensing applications. Although miniaturized vibration energy harvesters can provide an energy source for wireless sensing, major challenges are the energy harvesting capability, bandwidth, device size and reliability in harnessing broadband energy sources. The use of nonlinear dynamics features can play a key role in the design of the mechanical part of the harvester in order to increase its performance. Some fundamentals and methods adopted for this purpose are discussed in this seminar.
