Research project: Energy Harvesting

Currently Active: 

The objective of this research is to introduce nonlinear  damping to a harvester device to achieve better performance.

Energy harvesting using parametric excitation.

The aim of this project is to improve the performance of the linear harvesters by introducing a periodic time-varying parameter such as stiffness to the dynamic equation in order to generate parametric resonance. When the excitation appears as a time-varying coefficient in the equation of motion, the system is parametrically excited. A small parametric excitation can produce a large response when system is subjected to a frequency, twice one of its natural frequencies. The parametric oscillations could be used for energy harvesting.
