The researchers put […] … learn more→

Randomness and chaos in nature, as it turns out, can be a good thing – especially if you are trying to harvest energy from the movements of everyday activities like walking. Duke University engineers believe they have come up with the theoretical underpinning that could lead to the development of energy harvesting devices that are […] … learn more→
