New Tech For Prolonged Power In Computers, Smartphones
WASHINGTON: Scientists have developed a new technology that could lead to gen-next wearable computers with self-contained power sources and smartphones that do not die even after hours of heavy use.
The technology could reduce energy consumption in mobile devices and computers by tapping 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 at the University of Texas at Dallas found that by adding a specific atomic thin film layer to a transistor, the layer acted as a filter for the energy that passed through it at room temperature.
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 an author of the paper. "Our device is one solution to make this happen," said Kim.
Tapping into the unique and subtle behaviour of a single electron is the most energy-efficient way to transmit signals in electronic devices. Since the signal is so small, it can be easily diluted by thermal noises at room temperature.
