"Researchers at the University of Arkansas have just succeeded in creating a graphene circuit capable of" providing clean, unlimited low-voltage power to small devices or sensors ", although a famous theory claimed that it was impossible. "
This graphene circuit produces energy indefinitely
Will graphene one day establish itself as an ideal energy source to replace carbon? Many brands are indeed relying on this material to create new batteries, like Tesla or Samsung. Its many properties could even revolutionize water filtration in the long term. Nevertheless, the use of graphene to harvest energy is still subject to debate, since a famous theory by physicist Richard Feynman assumed that it was impossible to extract energy from Brownian motion, i.e. thermal motion. atoms.
Yet this is the hypothesis made by physics researchers at the American University of Arkansas, in a new study published in the journal Physical examination E. They explain having created " a graphene-based energy harvesting circuit that can be integrated into a chip to provide clean, unlimited low-voltage power to small devices or sensors. This circuit with the particular design (and detailed in the video below) made it possible, at room temperature, to produce an alternating current with graphene in monolayer form. Thanks to two opposing diodes, the researchers managed to circulate pulsed direct current, which is thus able to produce unlimited enough energy to power a small electronic circuit.
