This new gadgets can change the consumer electronic industry. Many completly new devices are possible in the future. (transparent wrist-watches, tablets, smartphones, e-readers). I think the Iphone-6 can be made with this technology!
“If you want to make everything transparent, what about the battery?” said Yi Cui, an associate professor of materials science and engineering and of photon science at SLAC National Accelerator Laboratory, renowned for his work with batteries.
The cost of these batteries are similar to regular batteries which are on the market today!
“If something is smaller than 50 microns, your eyes will feel like it is transparent,” said Yang, because the maximum resolving power of the human eye is somewhere between 50 to 100 microns.
Yang and Cui devised a mesh-like framework for the battery electrodes, with each “line” in the grid being approximately 35 microns wide. Light passes through the transparent gaps between the gridlines; because the individual lines are so thin, the entire meshwork area appears transparent.
