Cell Phones Can Use Self-Sustaining Power Supply Soon, Study
Chinese and Japanese engineering specialists have created a cell phone that might need hardly any charging, according to the Daily Mail.
Scientists find that "topological insulators" are newly discovered. They can build up an electrical current with no external source of energy.
Such a "non-lost energy" was found in the '80s, named the "Quantum Hall effect."
It required a cold climate, but now it can be duplicated in just room temperature.
While this new material is not a metal or an insulator but is a bit of both, its surface and edges have metallic properties, with the interiors behaving like an insulator.
An electrical current on the surface or edge can be created by a small film of this.
Hiroshima University scientists are undertaking the breakthrough study in order to drag renewable energy sources closer to real time devices such as cell phones.
"Hopefully, this achievement will lead to the creation of novel materials that operate at room temperature in the future," said Akio Kimura, a member of the research group and professor at Hiroshima University.
The findings were published in the Nov. 19 issue of the journal Nature Communications.
