RealFeedApp Graphene-based harvester uses magnetic fields from electrical wiring
Researchers from the University of Arkansas and the University of Michigan developed a graphene-based energy harvester that generates electricity from the magnetic fields of nearby AC wiring. The system powers a wireless temperature sensor via electromagnetic induction without batteries.
- Field
- energy and batteries
- What they did
- Scientists developed a graphene-based device that harvests electricity from the electromagnetic radiation emitted by nearby electrical wiring to power a wireless temperature sensor without batteries.
- Why it matters
- This enables the creation of truly autonomous monitoring systems that eliminate the need for battery replacement and can operate in locations where changing batteries is difficult or dangerous.
