Research

The broader spectrum of research on structural vibrations and the training I received at the Center for Intelligent Materials Systems and Structures during my PhD led me to start new research on energy harvesting technologies. Though my research contributions in this area are very recent, my publications in tier-one journals were featured in national media outlets. In December 2013, CBC Radio highlighted the wide-band hybrid vibrations harvester we designed, which employs two smart material solutions.

I performed collaborative research with Silicon Pro Co. in Ottawa to develop smart material solutions for self-contained sensing in smart grids. This sensing unit is used to detect power failure in transmission lines and relay this failure to a central processing unit via wireless communication channels. Our harvesting unit harvests minimal, yet sufficient, energy from the wires to ensure the sensor is self-contained. There is no need to rely on batteries for its operation.
