A team of researchers from the University of Texas has developed a technology that taps into the power of a single Power reduction at transistor-level is believed to be the first step towards the creation of wearable computers with self-contained power sources, or smartphones that do not easily drain their batteries even after a few hours of heavy use. The researchers found that by adding a specific atomic thin film layer to a transistor, the layer acted as a for the energy that passed through it at room temperature.
