Master's Thesis Research
George W. Woodruff School of Mechanical Engineering
For my master’s thesis, I am working on evaluating human motion for energy harvesting purposes using Piezoelectric Materials. This topic covers applications on three different scales:
- On-Body: energy harvesting from human motion for wearable devices
- Inside buildings: energy harvesting from human motion on the floors of buildings
- Infrastructure: energy harvesting from human motion over sidewalks and roadways
For this research, I have been looking into the forces the human body exerts during regular motion and then developing architectures that use these forces to harvest energy using piezoelectric materials. My research has resulted in the following publications and presentations:
