You may not think that charging your cell phone uses up that much energy, but think about how often you charge it. If you have a smart phone or other PDA, you may need to charge your phone every day. This can add up over the days. Your cell phone actually uses way more power than you think it does.
But what if there were some way to charge your cell phone without using traditional power? That’s what Kyocera, one of the larger cell phone manufacturers, has asked themselves. Kyocera designer Susan McKinney then took this idea and has created a conceptual device she calls the Eos. Her cell phone folds in thirds, is very flexible, and contains tiny piezoelectric generators. What do these generators do? Basically, as you walk and move, these nano-scale generators convert the kinetic energy of your body into power. While the device will most likely include a traditional charger, the power generated from your body may be enough to power the phone.
In addition to the nano-scale piezoelectric generators, the device has several other very innovative features. It uses shape memory that brings keys up from the surface of the device when it is in use and fade down when it’s not. The screen is also very flexible. It is about the size of a wallet when used for standard phone calls, but it can actually be unfolded to make a larger screen when you need to see more.
While we won’t be seeing this amazing device in stores just yet, Kyocera plans on making use of its many new features in the next few years, so expect to see flexible screens, shape memory, and even a few amazing kinetic energy-powered phones in the future.
