| Scientists are a clever and creative bunch. That’s kind of a prerequisite for being a scientist though. All the creativity and brain smarts can lead to some pretty crazy cool inventions, especially when it comes to the world of cell phones.A group of scientists in Korea have invented a cell phone battery that charges using the sound waves from your voice. That’s right, simply using your phone for what it was designed to be used for will keep your battery juiced up.
As far as the technology is concerned, the battery uses two pieces of zinc oxide placed between electrodes. The zinc oxide reacts to sound waves, creating an electrical current, which charges the batter. Now the next trick is to figure out how to get people to actually use their cell phones to talk to people rather than just text and surf the internet. I’m also curious as to whether or not the volume a person speaks at affects the speed with which the battery charges. People already scream into their bluetooth headsets and speaker phones as it is. I can only imagine how obnoxious it will be to listen to people shouting their conversation for the entire world to hear because they are low on battery life. Even better, I can’t wait to see people yelling random gibberish at their phone to keep it charged while they update their Facebook status. All joking aside, this would be a huge step forward in cell phone technology – an electrical device that charges by being used. |
