New technology tha prolonged power in mobile devices

New technology tha prolonged power in mobile devices

Researchers have created technology that could be the first step toward wearable computers with self-contained power sources or, more immediately that doesn't die after a few hours of heavy use.

Researchers from The University of Texas at Dallas have created technology that could be the first step toward wearable computers with self-contained power sources or that doesn't die after a few hours of heavy use. This technology, taps into the power of a single electron to control energy consumption inside transistors, which are at the core of most modern electronic systems.
Researchers from the Erik Jonsson School of Engineering and Computer Science also found that, the signal that resulted from the device was six to seven times steeper than that of traditional devices. Steep devices use less voltage but still have a strong signal.
"The whole semiconductor industry is looking for steep devices because they are key to having small, powerful, mobile devices with many functions that operate quickly without spending a lot of battery power," said Dr. Jiyoung Kim, professor of materials science and engineering in the Jonsson School and an author of the paper.
To create this technology, researchers added a chromium oxide thin film onto the device and filtered the cooler, stable electrons and provided stability to the device.
Another innovation used to create this technology was a vertical layering system, which would be more practical as devices get smaller "One way to shrink the size of the device is by making it vertical, so the current flows from top to bottom instead of the traditional left to right," said Kim, who added the thin layer to the device.
"Electronics of the past were based on vacuum tubes. Those devices were big and required a lot of power but our technology device is one solution to reduce such energy crisis as devices get smaller and smaller."  Dr. Cho said.
Researchers from the Lam Research Corporation in California, Nankai University in China, the University of Michigan and the University of Texas at Arlington contributed to this work.
