Harnessing Energy From Micro-vibrations And Temperature Differences
Researchers at MIT have been working to develop methods for harnessing energy from natural, passive processes.
Researchers at MIT have been working to develop methods for harnessing energy from micro-vibrations, attempting to maximize the efficiency of piezoelectric materials. The team envisions a world where sensors monitor data everywhere from pipelines and bridges to truck tires, where the constant replacement of battery-based power would be costly and inefficient. In studying new methods of generating energy, the team has been exploring the combination of piezoelectric technology with semiconductor materials that produce current when one side is hotter than the other, harnessing energy from differences in temperature.
