You Might Be Touching It Right Now
No matter what type of computer or device you're reading this article on, you're probably using some nanotech right now. Processors and memory components made with nanomaterials are common on the market, and you can find antimicrobial coatings on keyboards, mice and casings.
In coming years, we might start to see photonic crystals making tablet screens easier to read in daylight by changing the color of reflected sunlight, rather than relying on light projected by the device [source: NanoWerk]. Organic light-emitting diodes (OLEDs) are already lining up to replace the liquid crystal display (LCD) screen as the universal standard for smartphone displays. And a clear, thin coating of nanoparticles may one day save your smartphone from dying a watery death [source: Dillow].
Pretty soon, your electronics will run up to three times longer on a single charge just because tiny hairs called nanowhiskers are being built into their batteries [source: Ackerman]. By using tin in lithium ion battery anodes (tin is naturally covered in nanowhiskers), the anodes have a much greater surface area, which means they can store more electrons. That means more up time, longer cell phone calls and no more interrupting your Words With Friends benders just to plug in.
