Harvesting ambient energy will power IoT, scientists say

Stray, ambient magnetic fields that are naturally created from electricity usage should be captured, diverted, and converted into power for Internet of Things sensors, researchers say.

"Just like sunlight is a free source of energy we try to harvest, so are magnetic fields," said Shashank Priya, professor of materials science and engineering and associate vice president for research at Penn State, in a statement published on the university's web site. "We have this ubiquitous energy present in our homes, office spaces, work spaces and cars. It's everywhere, and we have an opportunity to harvest this background noise and convert it to useable electricity."
